摘要
Abstract
SPO2IDA method approximately estimates the incremental dynamic analysis curves by the backbone line of static pushover,which is a parameter analysis method based on static pushover analysis.SPO2IDA method extracts information from the static pushover curve and produces the necessary statistical estimation of the limit states'responses.On the basis of SPO2IDA method,puts forward a seismic fragility analysis method based on static pushover analysis,and uses this method to analyze the seismic fragility of the main building structure of a thermal power plant,and obtains the fragility curves of the structure corresponding to four limit states,and compares the results with those of the seismic fragility analysis method based on incremental dynamic analysis.The research shows that the seismic fragility analysis results based on static pushover analysis can provide reasonable and reliable seismic fragility data of the main building.关键词
