Currently, in probabilistic fragility analysis, the randomness of ground motion and material parameters is typically addressed by randomly combining several ground motions selected from seismic databases and sampled material parameters (Xu et al., Journal of Hydroelectric Engineering 37:31–38, 2018). However, this approach lacks coupling effects, suffers from insufficient sample sizes or involves extensive computational efforts, thereby limiting the acquisition of comprehensive probability information. There are few studies on the coupling randomness of ground motion and material parameters on the dynamic response of structures, and even less on the seismic response of high CFRDs.

摘要

Currently, in probabilistic fragility analysis, the randomness of ground motion and material parameters is typically addressed by randomly combining several ground motions selected from seismic databases and sampled material parameters (Xu et al., Journal of Hydroelectric Engineering 37:31–38, 2018). However, this approach lacks coupling effects, suffers from insufficient sample sizes or involves extensive computational efforts, thereby limiting the acquisition of comprehensive probability information. There are few studies on the coupling randomness of ground motion and material parameters on the dynamic response of structures, and even less on the seismic response of high CFRDs.
