<![CDATA[The application of digital image correlation (DIC) to capture any point in the experimental test is found to be promising. Using the DIC and appropriate tool can overcome the limitation of the traditional sensors to capture the movement or displacement in the tested specimen. In this study, an open-source DIC called Digital Image Correlation Engine (DICE) is used to capture the crack mouth opening displacement (CMOD) of the notched steel fiber reinforced concrete (SFRC) beam with points tracking method. There are three beam specimens with different sizes and similar aspect ratios reported in this paper. All beams have 0.5% steel fiber volumetric content. The SFRC beams are marked with points and tested under a three-point bending flexural test. Custom firmware for Canon DSLR 650D digital camera called Magic Lantern is used to capture the pictures per one second. DICE software is used to analyze the point movements and dumped the output file. ParaView 5.9.0 is then used to visualize the data. A method to calibrate the point coordinate with actual measurement is proposed. A small script is written in Visual Basic Application (VBA) in Microsoft Excel to correlate the displacement for each point of interest with the recorded applied load. With the developed script, any point of interest tracked with DICE can be related to the recorded data from the data logger. From this study, the obtained CMOD with the corresponding applied load is presented, which can be used to investigate the flexural fracture energy of the SFRC beam.]]>

<![CDATA[This paper presented a nonlinear finite element analysis of lateral loading RC shear walls with regular openings using the 3D-NLFEA program. The RC shear walls model was generated from the available test results in the literature. To model the concrete under a complex stress state, a multi-surface plasticity model which combines compression failure surface with tension cut-off failure surface was used. The model was intended to look at the load-displacement relationship and the crack pattern between the model and the numerical model. In addition to the numerical model verification, parametric studies were carried out to investigate the use of high-strength steel (HSS) of the two different grades (grades 100 and 120) to replace all the normal-strength steel (NSS) or only some of it. The parametric studies found that the shear wall with the NSS bar demonstrated higher stiffness and achieved higher lateral load with the lowest extent of damage (compared to the RC shear wall with the HSS bar). On the other hand, using the HSS bar resulted in lower stiffness, lower lateral load, and higher damage region, which was expected as more strain is required to yield the HSS bar.]]>

<![CDATA[The paper presents the effect of loading type on RC T-beam sections involving construction errors. This study involved 12 RC T- beams specimens divided into two main categories according to loading method. First category were loaded with uniformly distributed load at two-edges of slab while the second, were loaded with two-point concentrated loads at the middle length of beam specimen. The aim of this study is to evaluate, the effect of malposition of slab reinforcement, unequal configuration of slab reinforcement and change in bar diameter of slab reinforcement on the structural behavior of T-beam sections. The results indicated that malposition of slab reinforcement leads to a lower bending moment capacity of the slab. Flexural capacity of T-beams were higher than the rectangular beams where part of slab contributes to the resistance of the loads. Well-arranged distribution of reinforcement improves the ductile behavior of the slab and reduces the corresponding deflections.]]>

<![CDATA[The strengthening column structure elements with reinforced concrete jacketing were chosen in this study because it is the most common and easy to apply practically to existing column structures. Modeling data using test specimens from Ersoy et. al by adhering to constitutive models of concrete materials from Attard and Stunge and Bilinear steel. The purpose is to perform non-linear analysis modeling through the behavior of the section of the RC column reinforced with RC jacket by taking into account the influence of interface slip and initial strain by using a two-dimensional sectional analysis approach with a fiber-based method made using MATLAB. Non-linear analysis was performed to obtain the moment-curvature relationship and validate the modeling results with the experimental model then make modeling variations based on the variations high strength steel reinforcement and evaluate the results in curvature ductility and index ductility. The prediction results showed a fairly good fit with the experimental results and modeling variations showed that the greater value of interface slip coefficient, the higher the curvature ductility and index ductility, the variation modeling using high-strength steel in longitudinal reinforcement can increase flexural, axial and lateral capacity, but it is lower in ductility, while using normal strength steel for longitudinal reinforcement and high strength steel for lateral reinforcement with tighter spacing provides higher ductility.]]>

<![CDATA[Abstract: Pile foundation is a part of the Sub-structure that is used to receive and distribute loads from the superstructure to the ground at a certain depth, where it requires suitable bearing capacity. Empirical formula is the one of the methods for calculating pile bearing capacity that based on Standard Penetration Test (SPT) value. This method consumes plenty of time compared with the current method using Geo 5 software. However, the pile bearing capacity results among these methods should be verified beforehand. Therefore, it is necessary to do a comparison of pile bearing capacity laid on various soil types between the empirical formula and the Geo5 program based on SPT data to obtain the value of the correction factor and to find out which method is nearest to the Geo5 software. The Luciano decourt empirical method results are closer to the Geo5 software for all soil types, both of the end bearing and floating pile conditions with ratio values of 0.90 and 1.09 for dominant clay, 0.97 and 0.96 for dominant silt, and 0.84 and 0.89 for dominant sand. As for the Bazaara Empirical Method, the results are closer to the Geo5 program for the dominant group of sand in floating pile conditions with a ratio value of 0.99. Hence, the Luciano Decourt's empirical formula is more recommended than Bazaara's empirical formula.]]>

<![CDATA[Reinforced concrete shear walls are the main lateral load-resisting system in reinforced concrete structures. Shear walls have high stiffness when lateral load occur, especially due to earthquake loads. In the recent earthquake, the shear wall was damaged at the boundary eelment. The damage in boundary element is triggered by out of plane instability, concrete crushing, and reinforcement buckling. This study will evaluate the performance reinforcment concrete shear wall using the three-dimensional finite element method. Furthermore, the results obtained in this study will be validated firstly against the results of existing research. Based on the results of the study, the FEM validation process provides predictions that are in accordance with the experimental results regarding the hysteresis curve and the form of damage to the shear wall with an error value of 2.07% < 5%. However, the strain of shear wall elong the height of the wall has eror 26%.]]>

<![CDATA[This research is focused on modeling the damage of concrete due to corrosion. The load used in this paper is only focused on the internal load due to rust expansion. In this study, corrosion was modeled uniformly and non-uniformly to investigate the difference between these two configurations to the damage in concrete. The simulation in this study was carried out using the 3DNLFEA program. The results show that numerical simulation provides predictions that are in line with experimental and numerical modeling results performed by the previous study in terms of pressure and corrosion cracking patterns. From the crack analysis, the pattern found that a non-uniform corrosion model can be used to express a realistic rust corrosion development around the reinforcement. Meanwhile, uniform corrosion requires a larger loss of steel area to reach the damage stage. Therefore, for non-uniform corrosion, the corrosion rate cause cracks and reaches a limiting crack width at earlier times in the service life of the corroded part.]]>

<![CDATA[The Surabaya City Government seeks to provide adequate public transportation such as the Bus. The current condition on the Gunung Anyar - Kenjeran route is that there is no intermodal connectivity, so it is hoped that adequate intermodal connectivity will increase the demand for buses operating on the Gunung Anyar - Kenjeran route. For this reason, this research was conducted to plan the Microbus Stop as a stop location if the Microbus is to be used as a feeder for the Bus and determine the range of Microbus Stop services to meet the needs of the community. One of the locations chosen for this research is the Gunung Anyar - Kenjeran route, this is because this route is the route with the lowest number. Activities carried out to complete this research include conducting surveys of people who are active on and through the gunung anyar - kenjeran route, planning the alternative Microbus Stop location based on demand and infrastructure data and analyzing service coverage using the service area method. From the results obtained, it was found thatd majority of community made the move from Rungkut Sub-District to Gubeng Sub-District and Genteng Sub-District to Wonorejo Sub-District. Alternative Microbus Stop locations is divided into 2 schemes, namely demand-based and infrastructure-based. The demand-based Microbus Stop Scheme has 97 stop points while the infrastructure-based Microbus Stop scheme has 1270 stop points. Based on the results of the analysis of the service coverage of Microbus Stop, it shows that the infrastructure-based scheme has a better service area that meets community expectations, namely 5299.99 ha compared to the demand-based scheme which is only 1873.73 ha. The thing that causes the demand-based scheme to have a small service coverage area is due to the lack of demand data in Bulak District.]]>

<![CDATA[ChatGPT is an artificial intelligence that can understand context and respond appropriately. It could be used for research on a topic. However, ChatGPT does not always provide accurate information. Its performance has not been tested in engineering fields. In this study, ChatGPT was consulted about concrete-filled tubes (CFT), which is a structural element primarily subjected to axial load. Fifty-eight questions were posted to ChatGPT. ChatGPT’s responses (370 sentences) were evaluated. ChatGPT generated plagiarism-free statements, with only a 12% Turnitin similarity index. 78.6% of ChatGPT’s sentences were long and complex. Thus, Hemingway Editor gave them a Grade 14 for poor readability. The information given by ChatGPT can be classified as correct, erroneous, contradictory, and unverified. ChatGPT could be used as a research tool, but with limitations. It can explain the basic concepts of CFT but also provide inaccurate and contradictory information. A researcher needs to be cautious while using ChatGPT in research. ChatGPT could be used to test some hypotheses or theories. However, the quality of the output is dependent on the user’s critical inputs and an in-depth conversation with ChatGPT.]]>
