Performance Evaluation of Low-Rise Steel Structures Using Pushover Analysis (Case Study of Jeep Indonesia Brand Center Alam Sutera Showroom Building)

Abstract

Purpose: Indonesia is a country prone to earthquakes, and earthquakes can cause significant losses such as damage to infrastructure, buildings and loss of life. The objectives of this research are: (1) to determine the structural performance level of the Jeep Indonesia Brand Center Alam Sutera showroom building based on the ATC-40 method, (2) to determine the structural performance of the Jeep Indonesia Brand Center Alam Sutera showroom building based SNI 1726: 2019 regulations.

Methods/Design: The methods used in this research are: (1) 3D structural modeling using ETABS software, (2) calculate and determine the load on the structure based on SNI 1727: 2020, (3) perform earthquake load analysis to check the deviation between permit levels (∆) according to SNI 1726: 2019 regulations, (4) perform pushover analysis using ETABS software to obtain performance points, (5) evaluate the structural performance level using the ATC-40 method from the calculation of the drift ratio obtained from the performance point results.

Findings: The results showed that: (1) based on the performance points obtained, the maximum total deviation value for x direction = 0.01011 and y direction = 0.00858. While the maximum inelastic deviation value for the x direction = 0.00811 and y direction = 0.01085.

Practical implication: This shows that the performance level of the Jeep Indonesia Brand Center (JIBC) Alam Sutera showroom building structure based on the ATC-40 method is Damage Control (DC), namely the building suffered minor damage due to the earthquake, but the damage can be repaired at an affordable cost and the risk of human casualties is very small, (2) the performance of the building
