Abstract

We evaluated the performance of a high-rise residential building model in Purwokerto, Indonesia due to the seismic load. The evaluation was performed based on seismic loads given in the 2002 and 2012 Indonesian National Standard (SNI) using linear static analysis, dynamic response analysis and pushover analysis. Based on the linear static analysis, the drift ratio decreased by an average of 34.42 and 32.61% for the X and Y directions respectively. Meanwhile, based on the dynamic response analysis, the drift ratio also decreased by an average of 30.74 and 27.33% for the X and Y directions respectively. In addition, the pushover analysis indicates that the performance of this high-rise residential building model is still at Immediate Occupancy (IO) level. The post-earthquake damage state in which the building remains safe to occupy, essentially retaining the pre-earthquake design strength and stiffness of the structure. The risk of life-threatening injury as a result of structural damage is very low. Although some minor structural repairs may be appropriate, these would generally not be required prior to re-occupancy.

Highlights

These days, the demand for housing has increased because of the economic development and increase in population
The high-rise residential building is designed in such a way to maintain the vertical gravitational forces and withstand natural disaster such as an earthquake
The purpose of the current study is to assess the performance of the high-rise residential building model in Purwokerto, Indonesia because of the seismic load

Summary

Introduction

These days, the demand for housing has increased because of the economic development and increase in population. In this manner, Purwokerto is a locale with modestly high seismicity potential which needs to follow earthquake-resistant structural framework in every housing structure built up in Purwokerto. This will create awareness in the society or any parties
