The analysis of performance level on an existing multi-story building structure using the time history based on the subduction earthquake source

Abstract

The use of time history in the building evaluation process is rarely done. Usually, the time history used is taken from a different location, with the building being evaluated so that the evaluation results become less valid. Each place has a different time history character that is why the analysis of structures using time history from other sites is not accurate. In this study, the time history used was sourced from subduction earthquake sources. For the time history used in the location of the study, a spectral matching process is needed to equalize the response spectra of the time history with the response spectra at the study location. The Alana Hotel is selected as a research object for building evaluation adopting SNI 03-1726-2012, FEMA 356, and ATC-40 as references with structural modeling using SAP2000. Based on the evaluation results, it can be summarized that displacement values at each floor do not exceed the maximum limit so that this building has fulfilled the requirements. The inter-level displacement due to earthquake loading does not exceed the limit so that this building is feasibly occupied. The performance level of the Alana Hotel is Immediate Occupancy (IO).
