SVM Based Seismic Fragility Analysis for RC Isolated Continuous Girder Bridge

Abstract:

Because the fragility analysis methods used in recent years have some disadvantages to some extent, and there is no relative research report on the seismic fragility of structures based on SVM algorithm, nonparametric analytical method is used in the probabilistic seismic demand analysis, and fragility curves of RC isolated continuous bridge are obtained based on SVM Method. It turns out that the analytical results of SVM Method and Cloud Method are different in the longitudinal direction, matched in the lateral direction, and the results of the former method are greater than the latter one. It is a new and meaningful research that is more efficient than IDA method and also reliable.
