| Abstract: | For the sake of accurately considering structural uncertainties and defining failure modes,in simulating the process of structural catastrophe under strong earthquakes,a method for dynamic response analysis of nonlinear stochastic structures under stationary random excitation was proposed.By using the point estimate method,the double random vibration system was transformed into a series of determined nonlinear structures under stationary random excitation,then the mean and each order moment of dynamic respo... |
