Abstract

Areas in Indonesia are prone to earthquakes, so it is necessary to plan a structure that can withstand the lateral forces caused by the earthquake. Shear walls are very effective in resisting lateral forces due to their high stiffness. The purpose of the study was to determine the effect of the location of shear walls on structures subjected to earthquake loads according to SNI 1726-2019. 7 structural models were created, namely 1 model without a shear wall and 6 models plus a shear wall with the same area and location which were divided into 2 models each in the core area, transition area and edge area and analyzed with software ETABS. Results of analysis are time period, story drift and moments of column in all models are then compared. Obtaining the value of the small time period by placing the shear wall at the edge of the building, with the highest stiffness value. Obtain the value of the story drift in the direction of the small long axis by placing a shear wall in the core area of the building, with a relatively small stiffness value. While value of the short axis deviation story drift by placing a shear wall in the transition area with a small stiffness. Small column moments value by the location of the shear wall in the transition area has the smallest maximum column moment value with a relatively small stiffness. The rigidity of the frame structure is greatest by placing shear wall at the edges of the building.

Abstract

Pahandut Village in Palangka Raya City, Central Kalimantan, is experiencing rapid socio-economic growth, requiring accurate spatial data support for regional planning and management. Until now, the availability of spatial information at the Rukun Tetangga (RT) level, especially related to regional boundaries, infrastructure conditions, and the location of public facilities, is still limited and has the potential to hinder the process of formulating development needs. The Building and Impact Engineering (TMB) program activities are carried out to help overcome these problems through the preparation of spatial databases of urban villages. The implementation process uses qualitative and quantitative approaches, through field surveys and interviews to obtain data on RT/RW boundaries and public facilities. The collected data is then digitally processed using QGIS software, so that spatial information can be converted into digital maps and compiled in a geospatial format. The results of the visualization are then integrated into the website platform to facilitate access and utilization of information. The output of the activity is in the form of a website-based digital map that can be a more structured, accurate, and effective source of spatial data to support development decision-making in Pahandut Village

Abstract

The growth of high-rise buildings increases the demand for structural systems with high strength and stiffness. Concrete-Filled Steel Tube (CFST) columns, consisting of steel tubes filled with concrete, are a promising alternative. This study analyzes the equivalence of the reinforcement area in reinforced concrete columns to CFST wall thickness, evaluates the B/t ratio based on SNI 1729:2020, determines the required compact wall thickness, and compares structural responses in terms of lateral displacement and inter-story drift. A quantitative descriptive comparative method was applied using ETABS to model the Integrated Lecture Building of the University of Palangka Raya. Three models were analyzed: the existing reinforced concrete column (Model 1), the reinforcement-equivalent CFST (Model 2), and the SNI 1729:2020-based CFST (Model 3). Model 2 produced wall thicknesses of 1.874–3.532 mm with B/t ratios exceeding the λmax limit, indicating slender sections. Model 3 required wall thicknesses of 13, 9, and 6 mm to satisfy compact criteria. CFST columns reduced lateral displacement by 7.34–22.70% and inter-story drift by 6.63–23.07%.

Abstract

This study aims to design a Box Underpass Tunnel structure using the Ultimate Strength Design method to ensure structural safety, stability, and serviceability. The research applies a descriptive quantitative approach through technical analysis and structural calculations to evaluate the requirements and feasibility of a pedestrian underpass tunnel in the Bundaran Besar area, Palangka Raya City. The data utilized in this study consist of primary project data from the Menara and Bundaran Besar development obtained from the Public Works and Housing Agency of Central Kalimantan Province. The structural design uses K-300 quality concrete and U-41 reinforcing steel with a slab thickness of 45 cm. Structural modeling and analysis are performed using SAP2000 software to determine internal forces and reinforcement requirements. The analysis results show that the main reinforcement for the top slab is D19-50, wall slab is D19-150, and base slab is D19-50, while secondary reinforcement for all structural components uses D13-100. The findings confirm that the Ultimate Strength Design method provides an effective and reliable approach for designing Box Underpass Tunnel structures.
