Abstract

Fragility curves are the tools for evaluating the damage of structural or nonstructural components under different levels of ground excitation. It is also the necessary information for calculating the life-cycle cost of buildings during their design period. In this paper, development of fragility curves for buildings designed based on HK standard is presented. Two prototype models, which include three-storey and tenstorey reinforced concrete rigid frames, were considered. Incremental dynamic analysis was conducted under nine sets of past earthquake records with scaled peak ground accelerations. Maximum inter-storey drift ratio was selected as the damage indices and three performance levels were considered. Based on the numerical results, two fragility curves were developed to quantify the damage probability of RC buildings with different building heights.
