英文摘要	A performance-based method to calculate fragility functions of plane irregular RC frame-shear-wall structures was proposed. Using the method of performance-based static elastoplastic pushover analysis, according to definition of the ultimate damage states of the structure, four performance level limits of threshold values of inter-story drift angles and inter-story torsion angle were proposed. Structural seismic response was obtained through nonlinear dynamic time history analysis. Concerning conception of the probability of exceedance, the analytical solutions were proposed with performance level limits. Combined with the peak ground acceleration and the probability of exceedance, the performance-based seismic fragility analysis was carried out using this method, and fragility curves were derived to assess and compare the seismic performances of the structure. The results show that torsion response should be considered for analyzing irregular RC frame-shear-wall structures. © 2017, Central South University Press. All right reserved.
