Analisis Perilaku Struktur Perkantoran Tahan Gempa Menggunakan Metode Pushover Analysis

Abstract

A research about structural analysis of eight-story office building due to earthquake load and to identify the performance level of the structure referring to ATC-40. Performance Based Seismic Evaluation (PBSE) concept is used for earthquake engineering by using one of the method which is Pushover Analysis to evaluate the structure. This method is to purposely apply escalating static lateral load to the structure until failure occurs to the structural elements and targeted structural displacement was obtained. Determining the targeted displacement is referring to ATC-40, FEMA 365, and FEMA 440. Results show that targeted displacement value is 0,015 m for X direction and Y direction as well as the total drift was obtained as much as 0,0066 m for X direction and 0,00273 m for Y direction. According to the structural deformation and criteria from ATC-40 the performance level of the structure is at Immediately Occupancy (IO).
