| Abstract: | Based on stochastic finite element method,while structural response is calculated with the medal superposition method, probability information of structural response about the original random variables is got, bying applying the chain rule of differentation to the deterrnistic analysis. Dynamic realiability analaysis methods for structural system are given,that based on first order second moment approach. For an cxample,dguamic reliability is calculated for a tower carane. |
