【Abstract】 Based on the method of equivalent normalization for non normal variables, the 2D stochastic boundary integral equation is presented in this paper. The partial derivative over the random variables is prescribed. It makes the calculation of the structure’s reliability of multi variables and multi distribution problem possible. The random structural strength of material, the random characterized parameters of material and the random loads are considered. Two numerical examples show the effectiveness of the methods.更多还原
