Abstract

Abstrak Perencanaan ketahanan gempa untuk bangunan gedung sangat diperlukan sebagai konsekuensi kondisi geografi Negara Indonesia yang sebagian besar memiliki resiko gempa yang tinggi. Penelitian ini membahas kinerja struktur gedung laboratorium 5 lantai eksisting terhadap gempa kuat. Metode yang digunakan meliputi non-linier statik pushover dan non linier dinamik riwayat waktu (time history). Rekaman gempa yang digunakan digunakan adalah gempa kuat dengan percepatan spektrum 0.2 detik dengan rasio redaman 5% untuk periode 2500 tahun. Hasil analisis pushover level kinerja struktur saat performance point arah X termasuk kategori Immediate Occupancy dan arah Y termasuk kategori Damage Control dengan parameter sistem struktur hasil analisis non linier yang memenuhi syarat terhadap parameter desain SNI 1726-2019. Drift ratio terbesar pada analisis riwayat waktu menghasilkan level kinerja struktur dengan kategori Damage Control. Disimpulkan dengan kategori level kinerja struktur tersebut, saat terjadi gempa kuat (periode 2500 tahun) struktur akan mengalami kerusakan struktural yang ringan dan masih dapat diperbaiki untuk difungsikan kembali. Kata kunci: Desain berbasis kinerja, analisis non-linier, level kinerja struktur  Abstract Due to the geography of Indonesia, most of which has a high seismic risk, seismic design of buildings is necessary. This research discusses the structural performance of an existing 5-story laboratory building against strong earthquakes.  The methods used include nonlinear static pushover and nonlinear dynamic time history. The earthquake record used is a strong earthquake with an acceleration spectrum of 0.2 seconds and a damping ratio of 5% for a period of 2500 years. The results of the pushover analysis of the structural performance level at the performance point in the X-direction include the Immediate Occupancy category and in the Y-direction include the Damage Control category with the structural system parameters of the nonlinear analysis results that meet the requirements of the SNI 1726-2019 design parameters. The largest drift ratio in the time history analysis results in a structural performance level with the Damage Control category. It is concluded that with this category of structural performance level, during a strong earthquake (2500 year period), the structure will experience minor structural damage and can still be repaired to function. Keywords: Performance Based Design, Non-Linier Analysis, Structural Performance Level
