초록

Evaluating the seismic performance of a piloti-type structure is difficult considering the drift-based limit states such as interstory drift ratio and initial design review (IDR) of piloti-type structures are not defined. Drift-based limit states are defined for a lateral-resisting system, but piloti-type structures consist of two lateral-resisting systems. This study aims to analyze the suitability of existing drift-based limit states through the fragility assessment for piloti-type building structures. The piloti structures consisting of a shear wall system and a RC moment frame were used as a prototype model. IDR and concrete strain were used as the engineering demand parameter (EDP) to analyze the seismic fragility of target buildings through an incremental dynamic analysis (IDA). As a result of the correlation analysis of the seismic fragility curves obtained by IDR and concrete strain, the IDR-based limit states of a piloti-type structure should be lower than that of the practically used shear wall system.
