Abstract

The SPO2IDA method utilizes the backbone curve obtained from static-pushover (SPO) analysis to approximate the incremental dynamic analysis (IDA) curve. It is a parameter analysis method based on static-pushover analysis, and essentially represents an improved R-μ-T relationship. SPO2IDA utilizes the information obtained from the SPO curve to generate necessary estimates of various response statistics associated with the limit-state. In this study, the SPO2IDA method is combined with seismic fragility analysis, and the seismic fragility analysis method based on SPO2IDA is applied to assess the seismic behavior of the main building of a power-generation plant. The probability of exceeding four limit states for this structure is calculated using the SPO2IDA-based seismic fragility analysis method and compared with the results from an IDA-based seismic fragility analysis method. The research shows that the fragility analysis results based on SPO2IDA can offer robust scientific evidence for the prediction of seismic damage and losses of the main building of a power-generation plant.
