| Abstract: | In this paper, the reliability of orthotropic plate and beams composite structures, which is under the actions of the stochastic loading and stochasticboundary conditions, have been analyzed by stochastic boundary element method.First, the boundary integral equation of orthotropic plate and beams compositestructures is given in this paper, and then, based on the stochastic boundaryelement method, the method for reliability analysis of stochastic structures isestablished and formulas for computation of reliability index of orthotropic plateand beams composite structures are obtained. The computed examples show meefficiency of the method used in this paper. |
