Seismic fragility curves based on the probability density evolution method by Thuat-Cong Dang, Thien-Phu Le, Pascal Ray

“…In this paper, we propose a new technique for construction of seismic fragility curves by numerical simulation using the Probability Density Evolution Method (PDEM). From the joint probability density function between structural response and random variables of a system and/or excitations, seismic fragility curves can be derived without the log-normal assumption. …”
