Abstract

A storage building is a structure that has specified requirements for usage as a container or location anda high load value. As a result, it is crucial to check or examine the building's structure. There are two separateparts to the building structure, one of which is horizontal. Elements that bear loads working transversely andtransfer the load to a supporting column are known as horizontal elements, sometimes known as bending elements.It is crucial to assess the safety of horizontal elements like beams and slabs since they serve as the floor's bondingand reinforcing frames in superstructures. This final project attempts to assess the shear forces and momentsapplied to the floor slabs and beams, the reinforcement ratio applied to the beams, and the beam deflections thatresult. The presentation in this study makes use of ETABS v.17.0.1 software and secondary data. The 3rd floorhas the largest shear force in the X direction with a value of 59.3292 kN and the largest moment in the X directionwith a value of 128.9298 kN-m, while the 3rd floor has the largest shear force in the Y direction with a value of47.1916 kN and the largest moment in the Y direction with a value of 92.7026 kN-m. According to the result ofETABS v.17.0.1, the beam reinforcement ratio is 0.82 percent, and the maximum deflection permit limit formulauses SNI 2847:2019 to get the permitted deflection value of 25 mm.

Abstract

The construction of the Jakarta Kemayoran Tower was carried out using a mechanical coupler connection in the building column construction, because overlapping or conventional connections are not the right way to connect reinforcement. The main reinforcement in the column uses threaded iron with a diameter of 25. The mechanical coupler connection method used in this study is a coupler grip, with the planned tensile strength of the reinforcing steel being 525 N/mm². The column structure that is sampled is the main column with the size of the main steel reinforcement ≥ 32 mm. This study focuses on the analysis of quality tests and cost plans. The analytical approach used is descriptive analysis by looking for a comparison of the two variables. Testing the tensile strength of concrete reinforcement using a mechanical coupler connection showed successive results of 621.04 MPa, 624.86 MPa, 625.41 MPa, these results exceeded the minimum limit specified in SNI-2052-2017, namely 525 MPa. Meanwhile, the calculation of connection costs using the mechanical coupler method requires a total cost of Rp. 139,824,000, - while the cost of using a conventional connection is Rp. 191.161.127,-. From the calculation results, it is obtained that the difference is 37% cheaper than conventional reinforcement connections.This research can be used as a reference in alternative selection of reinforcement joints.

Abstract

This study explores the application of bamboo piles as a sustainable ground improvement technique in the construction of an athletic track at the Malabar National Athletic Training Center in Pangalengan, West Java. Utilizing a qualitative case study approach, the research documents the implementation methods, technical considerations, and performance outcomes of bamboo pile foundations in addressing geotechnical challenges posed by soft clay soils and high groundwater levels. The bamboo piles, made from Gigantochloa apus, were systematically prepared, treated with borax-boric acid for durability, and installed in a triangular grid pattern to enhance soil bearing capacity and minimize settlement. The integrated foundation system, combining bamboo piles with gravel layers, drainage systems, and a synthetic track surface, met the International Association of Athletics Federations (IAAF) performance criteria, achieving a bearing capacity improvement of 180-220% and maximum settlement of 12 mm. The approach offered significant economic benefits, with 35-45% cost reductions compared to conventional concrete piles, and environmental advantages, including a 60-70% lower carbon footprint. This research underscores the viability of bamboo piles as a cost-effective, environmentally friendly solution for specialized construction, bridging traditional knowledge with modern engineering practices. Recommendations for future applications include rigorous geotechnical investigations, quality control, and long-term performance monitoring to ensure reliability.
