A Comparative Study of Several Bio-inspired Algorithms in Cost Optimization of Cellular Beams
1Department
A Tjahjono1 , E J Wijayanti1 , D Prayogo1 and F T Wong1 of Civil Engineering, Petra Christian University, Surabaya, Indonesia E-mail: [email protected]
Abstract. Castellated beams are commonly used in steel construction. This study will focus on castellated beams with circular-shaped openings, which are known as cellular beams. Cost optimization of cellular beams is needed to maintain cost efficiency. The optimization considers the selection of a root beam, the diameter of holes, and the total number of holes in the beam as the variables. Four metaheuristic algorithms are used to optimize the design, namely, the particle swarm optimization (PSO), differential evolution (DE), symbiotic organisms search (SOS), and artificial bee colony (ABC). A four-meter span beam with a 50 kN point live load in the middle of the beam and a 5 kN/m uniformly-distributed dead load are taken as the case study. The results indicate that the SOS algorithm yields the best optimization results in terms of the average, consistency, and convergence behavior with a 30 out of 30 success rate.

The study of shear wall use in buildings during the architecture design process 1,2,3Department
Livian Teddy1, Husnul Hidayat2, and Dessa Andriyali A3 Architecture, Engineering Faculty, Sriwijaya University, Palembang, Indonesia Email: [email protected]
Abstract. In Indonesia, an earthquake-prone area, building designs must be earthquake resistant, and using shear walls is one of the ways to make buildings more earthquake resistant. However, determining the requirements and optimal position of shear walls is difficult. Miscalculating in their positioning can cause torsion and other unpredictable behavior. Previous studies were done to know shear walls’ optimal areas and positioning. The first way was trial and error, but this method was ineffective and took a long time. The second way, MATLAB programming, is actually very effective since the needs and orientation of the walls can be determined precisely. Nevertheless, not all structural engineers and architects master the programming language. This study, therefore, proposes relatively simple formulas and procedures to determine the optimal area and positioning of shear walls for architects preliminary design during architecture design process. The accuracy test for the formulas and procedures was carried out using ETABS simulation experiments on 10 building models with various irregular categories. The result showed the formulas and procedures proposed in this study were quite accurate in calculating the needs and position of shear walls. Optimal conditions, furthermore, were quite easy to achieve in symmetrical geometric compositions (1 or 2 axes) while organic or random geometric compositions were quite difficult to achieve. When the use of shear walls achieves optimal condition, the strength and stiffness of a building are increased, and the distribution of its strength and stiffness is relatively even, hence anticipating deformation behavior and reducing building eccentricity.

Modified Partial Capacity Design (M-PCD) Method 1
L S Tanaya1, Herryanto1, and P Pudjisuryadi1 Department of Civil Engineering, Faculty of Civil, Petra Christian University, Surabaya, East Java, Indonesia. E-mail: [email protected]
Abstract. Partial Capacity Design (PCD) has been developed by using magnification factor to keep some columns undamaged during major earthquake. By doing so, the structures will experience the partial side sway mechanism which is also stable, instead of the beam sidesway mechanism. However, in some cases, structures designed by PCD method failed to show the partial side sway mechanism since unexpected damages were still occurred at some columns. In this research, modification of PCD method is proposed by using two structural models in the design process. The first model is used to design beams and columns which are allowed to experience plastic damages, while the second model is used to to design columns which are intended to remain elastic when the strucutre is subjected to a target earthquake. Two nominal earthquakes corresponding to Elastic Design Response Spectrum (EDRS) level with seismic modification factors (R) of 8.0 and 1.6 are used in the first and second structural models, respectively. It should be noted that the second model is identical to the first model except that the stiffnesses are reduced for elements to simulate potential plastic damages. This proposed method is applied to symetrical 6 and 10 storey buildings with seismic load according SNI 1726:2012 and with soil classification of SE in Surabaya city. A Non-linear Static Procedure (NSP) or pushover analysis and Non-linear Dynamic Procedure (NDP) or time history analysis are employed to evaluate the performance of the structure. The evaluation is conducted at three earthquake levels which are nominal earthquake that is used in second model, earthquake corresponding to EDRS level, and maximum considered earthquake (MCER) specified by the code (50% higher than EDRS level). The building performances satisfy the drift criteria in accordance with FEMA 273. However, the partial side sway mechanism was not achieved at NDP analysis at maximum seismic load, MCER.

Abstract. The building appearance design is an architectural work that is supported by the structural design that it can display in accordance with architectural design. In order to achieve suitability, it is necessary to select a suitable structural system. For tall buildings a combined wall and frame structure is a suitable system. Shear walls modelling as planar or assembly have different assumption in behavior that will give other response in forces. Shear wall planar modeling as individual walls which each wall was modeled as a vertical beams. Wall assembly modeling as a combined unit to be represented by one beam element. The application of shear wall are placed in elevator shafts in buildings or stairwell. [1]. Computerized calculations are needed in determining the suitability in producing designs that are as close to the architectural appearance as possible. Using ETABS program, there are two modeling for planar and assembly with three design methods, this methods are Simplified Compression and Tension, Uniform Reinforcing and General Reinforcing. In this study, building model is 15- storey using dual structure system. This elevator shaft modelling into planar and assembly. The results are for longitudinal reinforcement the lower value is Uniform and General assembly, Uniform and General planar bigger 24,24 %, and Simplified Compression and Tension bigger 60,84 %. The transversal reinforcement have the same value for Uniform and General planar, Uniform and General assembly and Simplified Compression and Tension.

A Comparative Study of Several Nature-Inspired Algorithms in Steel Deck Floor System Cost Optimization T Emanuel1 , Hadrian1 , D Prayogo1, and F T Wong1 1Department of Civil Engineering, Petra Christian University, Surabaya – Indonesia E-mail: [email protected]
Abstract. Steel deck floor systems can be considered as one of the main components of a structure. As technology advances, the role of optimization is used in many aspects of structural designs. Steel deck floor systems are one of many components that are usually optimized to look for its optimum cost but are still able to hold the structure. This study compares the performance of the particle swarm optimization (PSO), artificial bee colony (ABC), differential evolution (DE), and symbiotic organisms search (SOS), that categorized as nature-inspired algorithms, in the optimization of a steel deck floor system. The variables considered are the edge beams, interior beams, and the composite steel deck. The results show that the SOS gives the most optimum cost with a better average and a perfect success rate.

Review of autonomous self-healing cementitious material 1Petra
S A Susanto1,, D Hardjito1,, A Antoni1, Christian University, Jalan Siwalankerto 121-131, Surabaya 60236, Indonesia E-mail: [email protected]
Abstract. Concrete is a well-known versatile material, and its application is very common in most structures. Concrete performance is high in compression but low in tensile strength, this leads to the appearance of microcracks when the structure bears the designed loading. Such microcracks when ignored, leaves the structure vulnerable to attacks such as seepage of water, chlorides, and other materials that lead to a reduction in performance, and extreme cases failure of the structure. Since cracking is inevitable in concrete, new materials with self-healing properties are introduced into the mixture to take advantage of the external materials while making the concrete stronger. This type of concrete is widely researched from 1970 until the present day and is still in ‘proof of concept stages, and very few to no applications of autonomous self-healing concrete in real-world structures. This paper is an attempt to further classify the existing methodologies and find the gaps between researchers. The autonomous healing of concrete in present-day research varies in results; this means that the self-healing methodology requires standardization. Furthermore, self-healing in concrete does not mean maintenance is not required, it implies an easier maintenance method is possible due to the benefits gained through a possibly higher early cost in construction.

Abstract. Architecture has a strong relationship with the daylight universe. It implicates further occupants’ behaviour toward visual comforts, healthiness, and energy consumption. The daylight simulation in the early phase of design benefits the architect in predicting the possibilities of daylight-related target goals during the design process. A shading system is one of the strategies in approaching passive design to prevent an excessive amount of undesirable daylight intensity. This paper investigates different sun louvers shading patterns and their relation to the Useful Daylight Illuminance (UDI) in the context of Indonesia, presented by incorporating the EPW file of Jakarta. Parametric and multiobjective optimization has been used to optimize, explore, and map the design possibilities based on the louver shading component as dynamic parameters. Rhinoceros and Grasshopper, as parametric-based modelling software, were used as the primary modelling platform, while the Honeybee and Ladybug plugin were used to undergo the daylightrelated environmental analysis. The design exploration iterates 2.160 design solutions with a value of dynamic parameters and the targeted UDI value embedded in each. The results show that the solution founded from iteration process has more areas of illuminance within 300 lx to 500 lx by about 15 %.

Abstract. Vertical greenery system (VGS) is commonly used for facade shading. It has many advantages in its natural aesthetic, air filter, carbon sequestration, and many more. This research is the continuation of the previous research in 2019, which used Shibataea kumasasa as VGS. It was found that using Shibataea as VGS has reduced the indoor air temperature by 0.5-20C on average, with 50C maximum temperature difference. On the other hand, it decreased more light (in range 26-95%), made the illuminance of the room lower than the standard requirement. A studio room should have minimum 5% daylight factor or 500 lux, while on the room measurement, the lowest was 20 lux in the morning hours, the highest was only 200 lux in the afternoon. As an attempt to look for vegetation with better performance, this research uses another bamboo species, Equisetum hyemale to be examined and then being compared to Shibataea. The result is that for the thermal shade, Equisetum performs less effectively than Shibataea. As for light shade, the Shibataea reduces more illuminance than Equisetum, thus makes it a less favorable alternative. The balance of thermal-light effective performance maintained by the leaf area index can be the focus of future research.

Abstract. The main problem related to thermal condition in Surabaya as a second-largest city in Indonesia is humid and hot. It is a typical condition of tropical climate. Ventilation in the hot day will bring warm and humid outdoor air into a room. It will increase the temperature of air in the room. One of some efforts to reduce the outdoor air temperature is using an earth to air heat exchange (EAHE) to transfer heat from the air to the earth or ground. This paper will discuss about research done to study the effect of EAHE to a room temperature. The study used two model rooms which are similar and a model EAHE. One room called condition room will receive air flowing from the EAHE pipe and the other room is called the referent room. From the research, it is found that the air in condition room with EAHE is cooler in the daytime compared to the referent room. The temperature of the condition room with EAHE is more stable.

Abstract. This study presents evaluation and comparison of simulationbased methods and metaheuristic optimization algorithms on building design models, focussing on daylight availability maximization and energy consumption minimization. The simulation-based method was presented using Rhino/Grasshopper software supported by the Ladybug, Honeybee, and Octopus optimization plugins; while MOPSO was chosen to calculate the metaheuristic optimization algorithm. The result indicated that OTTV values of the optimum design were respectively in the range of 24.06 W/m2to 34.15 W/m2for Octopus optimization and 25.19 W/m2to 34.99 W/m2for MPSO; and the WWR value for Octopus optimization and MOPSO were in the range 15% to 23% and 15% to 26%, respectively. While both methods showed similar results, the time duration for simulating in Rhino/Grasshopper was much longer compared to calculating the algorithm using MATLAB, indicating that simulation-based was less effective.

Abstract. In order to ensure that construction team works toward the desired objective, it is important for a project manager to behave as an effective project team leader. This paper aims to investigate actual and expected leadership of project managers by comparing the transactional and transformational leadership behavior model. To accomplish the objective, the paper first briefly reviews the ways in which leadership, especially the two models, are approached. Data were collected through a survey to 63 construction team members in several ongoing projects in Indonesia. The results indicate that the project managers frequently use both transactional and transformational behaviors in leading their team, except the laissez-faire style. Results from analytical hierarchy process analyses interestingly show that the project team members expect the project managers to exhibit transformational leadership more than transactional leadership.

The Uniformity Concept of Urban Design: Impact of Cultural Traditions on the Meaning of Balinese Town E D Mahira1, B Soemardiono1, E B Santoso1 Program, Department of Architecture Institut Teknologi Sepuluh Nopember, Surabaya, Indonesia E-mail: [email protected] 1Doctoral
Abstract. This study considers the conceptions of religion, tradition, and culture in the urban design process, to produce designs that become the identity of cities in Bali. A socio-semiotic approach is used to explore popular accounts of the conceptions of tradition operating in urban spatial arrangements from historical to contemporary periods. The case study in Gianyar City explores the meaning of urban space based on local wisdom that is still believed by Balinese people. Such exploration provides a basis for reconnecting urban designs with their cultural contexts, thereby promoting spatially expressed localism. Especially for Gianyar City, respect for religious systems, beliefs, and religions that have developed and are highly trusted by the public is expressed in symbolic elements that are embodied in the composition of space, and in fact, give rise to the concept of uniformity. This condition resulted in not achieving a more prominent urban cultural identity and being further damaged by the highly standardized process in the Indonesian planning system. However, the principles of religion and culture that are still alive make Balinese architecture alive, despite changing values, whether we realize it or not.

Abstract. Awareness of the increasing global issues regarding global warming and climate change has encouraged building designers to look back on knowledge of traditional architecture as energy-efficient and sustainable solutions. This study focuses on the traditional architecture of Rumah Kaki Seribu as sustainable architecture. Rumah Kaki Seribu is a traditional architecture located in the Arfak Mountains, West Papua, inhabited by the Arfak Tribe. Each architectural element of Rumah Kaki Seribu has a different sustainability value. The sustainability value of Rumah Kaki Seribu discussed is the concentration on the fireplace element and the roof element. The fireplace and roof elements were analyzed using the eco-cultural concept of the six competing logics of sustainable architecture by Simon Guy and Graham Farmer. Eco-cultural logic is a logic that is closely related to traditional architecture. The characteristics of sustainable buildings that use eco-cultural logic can be determined by looking at several parameters, namely the image of space, the source of environmental knowledge, the building image, technologies, and the idealized concept of place. The study aims to learn traditional architecture as a design approach to understand and respect the environmental context for solutions to global issues that occur.

An investigation into the effectiveness of student-led experiential learning for UG architects and the implications of incorporating AR into such pedagogical exercises. M Wallwork1, MA Tedjosaputro1, Weishun Xu2 1 University of Nottingham Ningbo China 2 Zhejiang University, China [email protected]
Abstract. This paper focuses on a collaboration between three researchers from two universities in Zhejiang province to explore the pedagogical value of hands-on experiential learning using non-standard materials (in this case, bamboo). The second aim of the project was to explore how Augmented Reality (AR) might be used to improve the efficiency of the learning process for the participants. As a building project, the outcome was largely successful- the undergraduate (UG) student participants were able to construct a 4-metre-tall bamboo structure in the summer of 2020, using active bending, from a 3D computer model, within the timeframe. They were given complete autonomy as part of the project which resulted in problems but also arguably improved the learner autonomy and problem-solving abilities of the respondents over the timeframe. Concerning the use of AR in such projects, this researched identified the value for this purpose but also some very major obstacles, including cost and complexity.

A study of place senses in museum online-visits Rully Damayanti1,*, Bramasta Putra Redyantanu1, Florian Kossak2 1Architecture Department, Petra Christian University Surabaya, INDONESIA 2HafenCity Universität Hamburg, GERMANY *corresponding author: [email protected]
Abstract. In the forced situation of living online during the recent pandemic, also human spatial perception needs to develop through experience and senses during online activities. People can go to new places using online media such as pictures, 360 panoramas, movies, Google Street View, and virtual tours while being physically separated and socially isolated. This also applies to museum visits when visitors can simply observe. This article offers data from a mixed-methods empirical study that examines how three Indonesian museums, Museum Pendidikan Surabaya, Museum Tsunami Aceh and Museum Bank Indonesia Jakarta, altered their perceptions in establishing a feeling of virtual space. The study has undertaken an identification of place descriptors related to senses multi-sensory systems. The respondents are young people in their twenties who have no prior museum experience. It demonstrates that in an online spatial experience, the respondents' perceptions are mostly influenced by the sensory system, which gets diverse information from the media, rather than social signals, which are frequently cited as the most important aspects in perceiving locations in real life. The component of familiarity (recalling memory) is also essential in detecting and identifying the sensory descriptors in this study. In an online spatial experience, all sensory systems perform differently; in this study, the visual and auditory sensory systems are the two strongest, while the chemical sensory system is the weakest.

Alternative approach in partial capacity design 1
Herryanto1,, L S Tanaya1, and P Pudjisuryadi1 Department of Civil Engineering, Petra Christian University, Surabaya, Indonesia. E-mail: [email protected]
Abstract. The Capacity Design Method is an approach widely used to design earthquake resistant structures. It allows the structures to dissipate earthquake energy by forming plastic hinges through beam side sway mechanism. In the design process, the columns need to be designed stronger than the beams connected to them. Several previous studies have been conducted to propose alternative method allowing partial side sway mechanism namely the Partial Capacity Design (PCD) Method. In this method, selected columns are designed to remain elastic and the plastic hinges are allowed to occur only at the columns base. These columns are designed to resist increased forces. Despite of some successful attempts, PCD method still needs to be developed because sometimes the intended mechanism was not observed. This study proposes a new approach to improve the Partial Capacity Design (PCD) method. Symmetrical 6 and 10 story buildings with 7 bays are analyzed using seismic load for city of Surabaya. Structure behavior under nonlinear static analysis is well predicted by this approach. However, under non-linear dynamic analysis, a few unexpected plastic hinges of elastic columns were observed at upper stories. But it should be noted that the earthquake used for performance analysis (maximum considered earthquake) is 50% larger than the one used for design (earthquake level corresponding to elastic design response spectrum).

P S Wulandari1 and D Tjandra2 Engineering Department, Petra Christian University E-mail:[email protected]
Abstract. Recycling tires is one of the eco-friendly way for reducing environmental problems. Incorporating crumb rubber in asphalt mixtures is an alternative way for reusing the end of life tires in road construction. The main purpose of this study is to evaluate the cold mix asphalt incorporating crumb rubber as a substitute for a part of fine aggregates. In this study, the aggregate gradations for mix design were selected according to the specification, Dense Graded Emulsion Mixtures (DGEM) Type IV and Open Graded Emulsion Mixtures (OGEM) Type E/20. The design bitumen content in this study was optimized for stability, void in mixture (porosity), and density. Crumb Rubber (CR) emulsion mixtures were made with optimum bitumen content at 8% by mass of total mixture for DGEM and OGEM. In order to incorporate crumb rubber into the cold emulsion mixtures, laboratory testing were performed for 25% and 50% of fine aggregates replaced with an equal volume of crumb rubber. In general, CR emulsion mixtures showed good results in all parameters. The CR emulsion mixtures also had a good comparison to hot mix asphalt specification for medium volume traffic loads with porosity less than 10%. From this study, crumb rubber can be recommended as a substitution material of fine aggregates in cold mix asphalt.

Abstract. Three-dimensional (3D)-printed concrete is believed to have a significant impact in the construction industry in the future. Some research has been conducted experimentally and analytically to investigate the structural behavior of 3D-printed concrete elements, such as beams. Previous study by the authors attempted to analytically model 3D-printed reinforced concrete (RC) beams failing in flexure that were tested by other researchers. The study was done with the aid of a finite element software. However, there are some limitations of the analytical model to simulate the failure mode of the specimens. In this study, an improvement of the analytical model is proposed in order to simulate the behavior of the 3D-printed RC beams more accurately. Furthermore, the analysis was also expanded for 3D-printed prestressed concrete (PC) beam. From the analysis results, it can be concluded that the improved analytical model is able to predict more accurately the failure mode as well as the hysteretic behavior of the 3D-printed RC beams. Nevertheless, a more sophisticated analytical model is needed to improve the accuracy of the prediction for the 3D-printed PC beam. Keywords: analytical model, 3D-printed RC beam, 3D-printed PC beam, hysteretic behavior.

Abstract. Damages resulted from earthquakes are a loss in the economic sector. The structure of multi-story buildings needs an earthquake-proof design with higher performance to reduce such losses. By utilizing the metaheuristic algorithm, this study aims to identify the most compatible brace configuration and profile used in a concentrically braced steel frame structures with minimal total weight and that will meet the safety requirements. This algorithm is suitable owing to the fact that it is able to find solutions to any known optimization problem either through Particle Swarm Optimization (PSO), Symbiotic Organisms Search (SOS), or Differential Evolution (DE). The performance of these algorithms will demonstrated in a form of comparison through a case study of optimizing a 5-span, 6-story steel frame structure. These systems will determine the lightest frame weight, which also correlates to a lower construction cost, without compromising the constraints of SNI 1726:2019, SNI 1727:2020, SNI 1729:2020, and AISC 341-16. Based on the results of data processing, SOS is shown to achieve the highest algorithm performance compared to PSO and DE.

Investigation of the material mixtures and fiber addition for 3D concrete printing A Antoni1,*, A Agraputra1, D Teopilus1, A H Sunaryo1, M M Mulyadi1, P Pudjisuryadi1, J Chandra1 and D Hardjito1 1 Civil Engineering Department, Petra Christian University, Surabaya, Indonesia * Corresponding author: [email protected]
Abstract. The era of Construction 4.0 is characterized by technological advances used in the construction industry. One of the advancements is the use of 3D concrete printing in construction. However, until now, the development of 3D concrete printing in Indonesia is still minimal. The main challenge is to determine the composition of the material mixtures for making the mortar, having good extrudability but still has sufficient strength. The rapid initial setting time required was also different for the concrete for typical construction. Our previous mixture composition incorporating calcium oxide to accelerate the initial setting time was adequate. However, the extrusion process was still not satisfactory. In this study, the effect of cement to sand ratio, sand particle size, and the addition of synthetic micro-fiber was investigated on the main properties of 3D printing materials, i.e., initial setting time, flowability, extrudability, and compressive strength. It was found that using smaller maximum particle size sand increases the initial setting time. The addition of synthetic microfiber reduces the strength and the workability of the mortar. However, fiber inclusion has advantages as it reduces the possibility of cracking in the printed concrete. The extruded concrete specimens were shown to have significant strength reduction due to lack of compaction, and it was affected by the direction of printing showing orthotropic properties of the 3D printed concrete

Abstract. To some people, back-in parking maneuver is a relatively hard thing to do. However, previous studies have proven that back-in parking is safer than head-in parking because when exiting the parking space (back-out) from head-in parking, the driver's field of view is more limited, thus increasing the chance of an accident. This study aims to determine the changes in the driver's viewing frequency on the rearview mirror, maneuver duration, and degree of difficulty during back-in parking maneuvers. Data collection was obtained from 45 participants who tried to park their cars in a parking space with an angle of 30°, 45°, 60°, 90°, each with four different conditions of parking spaces. The driver’s viewing frequency on each rearview mirror (left, right and center) and maneuver duration were obtained from a dashcam and an external camera recording. The difficulty level for maneuvering was filed according to the driver’s opinion during the experiment for each parking space condition. Based on the data analysis, it was proven that the existence of cars parked on either side of that parking space (obstacles), parking space line signs, and both simultaneously increase the driver’s viewing frequency and maneuver duration when doing back-in parking maneuver, but at the same time, ease the parking maneuver, according to the driver.

Abstract. Traffic accidents involving animals occur every year. Roadkill is a serious problem faced by the whole world, including Indonesia. Therefore, it is necessary to modify road accessories to prevent accidents, both from animals and road users. Prevention can be done in several ways, such as by installing fences or creating crossing paths, for animals. The fence can be used as a barrier between the driving lane and the animal path, where they can carry out activities such as playing without disturbing road users. Meanwhile, the making of crossing paths can be used by animals as access for animal migration. This study would like to propose a design for implementing cross-fencing mitigation at Gladak Perak Bridge at Lumajang, Indonesia. This location is an accident-prone area due to the sudden crossing of monkeys, which has been a myth in the community. Through the implementation of the installation of road dividers, it is hoped that the road design at the research site becomes wildlife friendly road and the management of traffic also meet the Indonesian design standards for inter-city roads without reducing tourism potential. Keywords: roadkill, monkey, sustainable, mitigation, crossing-fencing, Gladak Perak

Abstract. The determination of tariff is necessary for a city willing to implement electronic road pricing such as Jakarta. Therefore, this study was conducted to investigate the effect of household characteristics on the willingness and probability to pay more than IDR 20,000. The focus was on those commuting to work within the city where the majority of people work in the formal sector. Moreover, the Willingness to Pay IDR 20,000 was proposed as a variable while age, number of family members, income, vehicle ownership and the work type were used as the explanatory variables. The results showed the general effect of households in receiving ERP rates was low as indicated by the 16.9% recorded. However, family with total members of 4-5 people and owning a vehicle was observed to have a partially great and significant probability to increase the willingness to pay tariffs > IDR 20,000 while those earning income
