Stochastic boundary element method for reliability analysis of plate and beams composite structures

In this paper, the reliability of orthotropic plate and beams composite structures,which is under the actions of the stochastic loading and stochastic boundary conditions,have been analyzed by stochastic boundary element method. First, the boundaryintegral equation of orthotropic plate and beams composite structures is given in thispaper. and then based on the stochastic boundary element method, the method forreliability analysis of stochastic structures is establishes and formulas for computationof reliabilily index of orthotropic plate and beams composite structures are obtained.The computed examples show the efficienl of the method used in this paper.
