Abstract

Pada tulisan ini penulis meninjau ulang respon spektra percepatan gempa dipermukaan tanah yang diperlukan sebagai parameter penentuan beban gempa rencana pada perencanaan struktur bangunan tahan gempa berdasarkan SNI 03-1726-2019, yang merupakan peraturan pengganti SNI 1726 2012, dimana pada peraturan SNI 1726;2019 menggunakan peta hazard gempa Indonesia 2010 dengan percepatan gempa terpetakan periode pendek (SS ) sebesar 0,264.g dan percepatan gempa terpetakan periode 1 detik (S1) sebesar 0,164.g, sedangkan pada SNI 1726;2019 yang merupakan SNI pengganti besar percepatan gempa terpetakan periode pendek (SS) dan (S1) secara berurutan nilainya adalah 0,3.g dan 0,25.g. Dari hasil analisa didapatkan nilai respon spektra percepatan, Sa (g) meningkat walaupun faktor amplifikasi untuk wilayah kota palembang mengalami penurunan khususnya pada lokasi tanah sedang (SD) dan lunak (SE). Peningkatan respon spektra disain periode pendek (SDS) untuk tanah keras, lunak dan sedang secara berturut-turut adalah sebesar 23%, 12%, dan 5% sedangkan untuk respon spektra disain periode 1 detik (SD1) adalah sebesar 39%, 49%, dan 40%. Ini mengindikasikan bahwa beban geser dasar gempa pada perencanan struktur tahan gempa tentunya juga akan mengalami peningkatan pada perioda struktur, T < Ts atau T > Ts.

Abstract

His study discusses the structural design of a 13-story hotel building in Batam City, which effectively prevents structural failure due to earthquakes based on the Response Spectrum obtained for the Riau Islands, Batam City. The Special Moment Resisting Frame (SMRF) system is used in accordance with SNI 1726:2019. The building, measuring 55 × 21 meters with a height of 46 meters, utilizes concrete with a compressive strength of 30 MPa and reinforcing steel with a yield strength of 420 MPa. The objective of this study is to develop a reinforced concrete structural model for the 13-story hotel building that complies with the requirements of SNI 1726:2019 and to ensure the reinforced concrete design meets the provisions of SNI 2847:2019. This research employs the linear equivalent method with numerical and computational analysis to calculate the structural response under static-dynamic loading. The earthquake load analysis yielded vibration periods and frequencies of Tcx = 2.77 seconds and Tcy = 2.81 seconds, respectively. The maximum value of Cu·Ta obtained is 2.046, using T = 1.91 and T = 1.99. The performance results for the ultimate inter-story drift limits in the x and y directions are smaller than the allowable limit ∆s, indicating that the serviceability performance is safe.

Abstract

Structural concepts in the planning and evaluation of building structures for earthquakes emphasize performance, resilience, and rapid recovery. One such approach is performance-based design, known as Performance-Based Earthquake Engineering (PBEE). This research aims to design the structural system of a mental hospital building against seismic loads according to SNI 1726:2019 and to analyze the performance level of the specialized Psychiatric hospital structure following a design-level earthquake. The analysis was conducted by evaluating gravity loads, applying the equivalent static force method, performing response spectrum analysis, modeling the structure using ETABS, and checking the structure for strength, stiffness, and stability. The structural performance was evaluated using a non-linear pushover analysis. The results of this study indicate that the performance level of the Psychiatric hospital building structure, when subjected to a displacement of 0.59 m, exceeds the Collapse Prevention (CP) level.

Abstract

High-rise buildings are highly vulnerable to the effects of lateral loads, particularly seismic loads. One important phenomenon that must be considered in structural design is the P-Δ (P–delta) effect. This effect occurs due to the interaction between axial forces in structural elements and the lateral displacement of the building, which generates additional moments. These additional moments can increase structural deformation and reduce overall stability. In multi-story buildings, especially those with more than 10 floors, the influence of the P-Δ effect becomes more significant because of the large axial forces in the columns combined with relatively high lateral displacements. This study aims to analyze the influence of the P-Δ effect on the behavior of high-rise building structures using numerical analysis based on the seismic design standards applied in Indonesia. The scope of the study focuses on modeling multi-story building structures with the aid of structural analysis software, with variations in the number of floors, to determine the extent of the P-Δ effect on lateral displacement, internal moments, and structural safety factors. The results of the analysis are expected to provide a deeper understanding of the significant role of the P-Δ effect in seismic-resistant building design. These findings are also intended to serve as a reference for designers and civil engineering practitioners in ensuring that high-rise building designs remain safe, stable, and compliant with applicable regulations.

Abstract

Education is the fundamental foundation for developing high-quality human resources. Along with the rapid development of the modern era, improving the quality of education has become essential, both in terms of curriculum, teaching staff, and supporting facilities. One of the most important aspects is the availability of educational buildings that are safe, comfortable, and compliant with technical construction standards. This study discusses the design of a ten-story reinforced concrete building using a Special Moment Resisting Frame (SMRF) system. The design was carried out in accordance with SNI 2847:2019 on Structural Concrete Requirements for Buildings and SNI 1726:2019 on Earthquake Resistance Design for Buildings and Non-Buildings, considering that the construction site is located in an earthquake-prone area. The structural analysis was conducted using modern structural analysis software, which included evaluating internal forces, deflections, and beam–column interactions under seismic loads. The results show that the designed structure performs well and meets all safety and serviceability requirements. The shear capacity of beams and columns satisfies the provisions of SNI 2847:2019, ensuring that the structure demonstrates a high level of reliability in resisting seismic forces. Therefore, the findings of this study indicate that the implementation of SMRF in high-rise educational buildings can serve as a safe, efficient, and standard-compliant design solution.
