Abstract：The ground-motion selection is neglected on the traditional fragility demand curve of structural seismic engineering, and the seismic hazard is rarely considered. The conditional mean spectrum (CMS) ground-motion selection method was introduced into the IDA method and stripe method to solve the problem, and compared with the traditional cloud method with disperse ground-motion records. Conditional mean spectrum was constructed based on the China seismic disaggregation result and attenuation relationship. The fragility demand curves and the demand hazard curves of one eight-stories 2D structure were computed using the three different methods. With the two different ground-motion records selection as the input of the traditional cloud method, the two group results are significant variation. Considering the merit of CMS selection in IDA method and stripe method, the results are coherence and could be applied in the subsequent loss estimation study in performance based earthquake engineering.
