Abstract

Indonesia lies within the Pacific Ring of Fire at the convergence of three major tectonic plates, making earthquake-resistant design a critical challenge for multi-story buildings. Structural systems such as reinforced concrete shear walls and steel bracing are commonly employed to enhance lateral load resistance. This study evaluates and compares the seismic performance of shear wall and bracing systems in a three-story residential flat located in Silangkitang Village, North Tapanuli, using nonlinear static (pushover) analysis conducted in ETABS v18. The analysis results indicate that, in the X-direction, the shear wall structure achieves a total displacement of 66.84 mm with a base shear of 8512.78 kN, whereas the braced structure exhibits a total displacement of 119.19 mm with a base shear of 9773.20 kN. In the Y-direction, the shear wall structure records a total displacement of 166 mm and a base shear of 13,228.69 kN, while the braced structure achieves 173 mm and 8210.53 kN, respectively. These findings demonstrate that, although both systems satisfy the same structural performance level criteria, the shear wall system provides superior lateral stiffness and more favorable displacement characteristics compared to the bracing system.

Abstract

This study evaluated the seismic performance of flat slab structures designed according to four international standards: SNI 2847-2019 (Indonesia), NZS 3101:2006 (New Zealand), IS 456-2000 (India), and JSCE 15-2007 (Japan). A five-story reinforced concrete building was modeled using ETABS for nonlinear pushover analysis, while MATLAB was utilized for calculating slab thickness, moment distribution, reinforcement design, and punching shear strength. Results unveiled that the JSCE 15-2007 code provided the stiffest system with minimal lateral displacement and the highest base shear capacity, whereas IS 456-2000 exhibited superior ductility and flexibility. SNI 2847-2019 and NZS 3101:2006 delivered balanced performance in terms of stiffness and material efficiency. The variation in slab thickness, reinforcement area, and natural period highlighted each code’s design philosophy regarding seismic safety. These findings suggest that code selection should consider regional seismic risk, structural demands, and construction priorities to ensure optimal safety and efficiency. The study contributes to the harmonization of global flat slab design practices and offers practical recommendations for improving the seismic resilience of buildings.

Abstract

Pilecap merupakan elemen pondasi yang tergolong daerah diskontinuitas (D-Region) sehingga distribusi tegangannya tidak dapat dianalisis secara akurat menggunakan teori lentur konvensional. Penelitian ini bertujuan menganalisis perilaku aliran gaya, mengevaluasi kapasitas pilecap beton bertulang menggunakan Strut-and-Tie Model (STM), serta mengkaji pengaruh penerapan lebar efektif terhadap efisiensi desain pada Proyek Pembangunan Pabrik Kertas Tanjung Morawa. Metode penelitian meliputi analisis elemen hingga menggunakan SAP2000 untuk memperoleh lintasan tegangan utama, penyusunan model STM, perhitungan kapasitas strut, tie, dan zona nodal berdasarkan SNI 2847:2019, serta verifikasi menggunakan perangkat lunak Computer Aided Strut and Tie (CAST). Hasil penelitian menunjukkan bahwa aliran gaya tekan utama membentuk jalur diagonal dari kolom menuju kelompok tiang, sedangkan gaya tarik terkonsentrasi pada serat bawah pilecap. Verifikasi menunjukkan rata-rata force ratio hasil perhitungan manual sebesar 0,64 dan hasil CAST sebesar 0,63 sehingga model yang dikembangkan dinilai konsisten dan andal. Penerapan lebar efektif dengan mengurangi lebar kerja pilecap dari 2600 mm menjadi 1800 mm meningkatkan rata-rata force ratio dari 0,63 menjadi 0,82 tanpa melampaui batas kapasitas struktur. Disimpulkan bahwa integrasi STM, analisis lintasan tegangan, dan verifikasi CAST mampu menghasilkan desain pilecap yang lebih rasional dan efisien. Pendekatan ini direkomendasikan sebagai alternatif perancangan pilecap beton bertulang pada D-Region sesuai ketentuan SNI 2847:2019.

Abstract

Reinforced concrete column design is the process of determining the dimensions of the columns and reinforcement required with the appropriate quality of concrete and steel so that they can withstand the planned load to work on the column. Unlike the beam design, which was based on the applied load, it is possible to determine the cross-sectional dimensions and reinforcement requirements directly from the design equation, and the column design process is iterative. A column generally experiences axial forces, shear forces, bending moments, and torsional moments. In this paper, cross-sections of reinforced concrete columns are modelled and analyzed using an android application that can be installed via the play store. The application offered by eigenplus named RCC Column Design version 2.1.12 was released on 17 September 2017. The last updated RCC Column Design application was on 25 March 2018. This paper aims to predict the cross-sectional capacity of reinforced concrete columns with variations in reinforcement diameter. The cross-sectional capacity of the column referred to in this paper is the axial capacity, moment capacity, and shear capacity. Furthermore, the value of the cross-sectional capacity of reinforced concrete columns with variations in the diameter of the reinforcement has been obtained. The values ​​obtained are proposed as predictions in this paper.
