000019387 520__ $$2eng$$aA simplified evaluation method for the seismic fragility of subway stations is presented in this paper. Pushover-method, as an effective method, is wildly used and has been evaluated by many researchers. Recognizing that the nonlinear history analysis of underground structures is extremely computational demanding, this paper presents a pushover-based evaluation method for the seismic fragility of subway stations in the following steps: 1. determining the structural damage index and classifying the structural performance levels; 2. conducting pushover analysis of the subway station; 3. selecting seismic records; 4. calculating the target displacement of every seismic record; 5. conducting probabilistic analysis and expressing the structural motion-damage relationship by means of fragility curves. Additionally, the pushover-based seismic fragility analysis of Daikai subway station, which was greatly destroyed in 1995 Great Hanshin Earthquake, is introduced as an example.
