摘要
本文用随机边界元法分析了随机荷载作用下具有随机边界条件的正交各向异性板、梁组合结构的可靠性．文中首先给出正交各向异性板、梁组合结构的边界积分方程，进而基于随机边界元法建立了随机结构可靠性分析方法和得到用于计算正交各向异性板、梁组合结构可靠性指标的公式．算例表明了本文方法的有效性．
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.
