Abstract

Periodical seismic safety evaluation for concrete buildings are necessary since they have been used for many years. Many approach can be used to evaluate them, one of them is pushover analysis. This analysis is performed by applying incremental loads then reading the displacement that happen, and comparing it to the response spectra demand to retrieve the performance point. Moreover, time-history records can be used to determine the displacement appear in structure. This study aims to perform 3D evaluation of reinforced concrete buildings. The selected building sample was one academic building in Yogyakarta, Indonesia which has 7 storeys. The analysis was performed using STERA 3D software. Three time-history records namely El Centro, Kobe, and Parkfield earthquakes were used to determine the displacement. These records were matched with response spectrum for Yogyakarta based on Indonesian earthquake resistant building code. The result shows the performance level of the building and the displacement resulted from inputting time history, compared to the displacement limit. It is hoped that from this study, related stakeholders can take necessary actions if needed and can be the reference for future further studies.
