| Abstract: | MATLAB, a simple and convenient method incorporating first-order second-moment, Monte-Carlo Method and PSO, is developed to calculate structure reliability. It is also proposed to calculate geometric reliability with divided mesh method and coarse divided mesh method that can avoid dimensional disaster. When using parallel coarse divided mesh method to calculate geometric reliability, the exterior penalty function is introduced to transform constrained optimization into unconstrained optimization. |
