Evaluasi Kinerja Seismik Gedung Inkubator Bisnis Halal IPB Menggunakan Metode Pushover Analysis Berdasarkan ASCE 41-17

Abstract

Kota Bogor memiliki risiko bencana gempa bumi menengah dengan potensi guncangan V–VIII MMI. Penelitian ini mengevaluasi kinerja seismik Gedung Inkubator Bisnis Halal IPB menggunakan Nonlinear Static Procedure (NSP) berdasarkan ASCE 41-17 pada tingkat gempa BSE-1E (kala ulang 250 tahun) dan BSE-2E (kala ulang 1000 tahun). Hasil analisis menunjukkan kapasitas lateral gedung aman di seluruh arah peninjauan, dengan periode getar efektif arah X sebesar 0,87 detik dan arah Y sebesar 0,95 detik. Perpindahan target maksimum terjadi pada arah Y akibat beban BSE-2E sebesar 211,82 mm. Mekanisme sendi plastis memenuhi prinsip Strong-Column Weak-Beam yang dimulai dari balok lantai 1. Seluruh komponen force-controlled aman dengan DCR < 1,0. Secara global, kinerja simpangan arah X memenuhi level Immediate Occupancy (IO), sedangkan arah Y memenuhi level Life Safety (LS) dengan drift total maksimum 1,30%.

Bogor City exhibits a moderate earthquake risk with a potential shaking intensity of V–VIII MMI. This study evaluates the seismic performance of the IPB Halal Business Incubator Building using the Nonlinear Static Procedure (NSP) based on ASCE 41-17 under BSE-1E (250-year return period) and BSE-2E (1000-year return period) levels. The analytical results show that the building's lateral capacity is safe in all directions, yielding effective fundamental periods of 0.87 seconds in the X-direction and 0.95 seconds in the Y-direction. The maximum target displacement occurs in the Y-direction under BSE-2E loading at 211.82 mm. The plastic hinge mechanism satisfies the Strong-Column Weak-Beam principle, initiating at the first-floor beams. All force-controlled components are declared safe with a DCR < 1.0. Globally, the drift performance in the X-direction meets the Immediate Occupancy (IO) level, while the Y-direction satisfies the Life Safety (LS) criteria with a maximum total drift of 1,30%.
