Seismic Fragility Curves: A Comparison Among Nonlinear Static and Dynamic Analysis Procedures
Nonlinear response time-history analyses are used in well-known seismic performance assessment methods such as Incremental Dynamic Analysis, Multi-Stripes Analysis and Cloud Method to describe the relationship between chosen Damage Measure versus Intensity Measure. Numerous researches have presented simplified procedures or nonlinear static procedures to develop fragility over the last two decades. In NSPs, pushover analysis is used to assess the system capacity, and response spectra quantify the seismic demand. In addition to the known ones, Incremental Modal Pushover Analysis (IMPA) is a novel nonlinear static procedure that has been proposed in recent years and is used in this study to advance an IM-based fragility estimation. The accuracy and effectiveness of various vulnerability assessment methods are investigated by comparing fragility curves obtained from MPA-based Cloud Analysis, IMPA, Cloud Analysis to IDA fragility curves. The results from two relatively small bins of record motions differing by ranges of Joyner-Boore Distance and are scattered across a range of Magnitude are presented.
