MATLAB在结构可靠度分析中的应用

Applications of Matlab in Structural Reliability Analysis

以某砌石重力坝为例,利用结构可靠度计算方法中的JC法和Monte-Carlo法进行可靠度分析,建立结构功能函数,利用MATLAB数学软件分别对JC法和Monte-Carlo法进行编程计算,得到砌石重力坝的失效概率与可靠度指标.运行结果表明运用MATLAB编程计算精度较高,运行速度较快.

For a masonty gravity dam as an example,we used the structural reliability calculation method on reliability analysis that contain the JC method and Monte-Carlo method,and established the structural function.The calculation progams are based on JC method and Monte-Carlo method respectively by using the mathematical software of Matlab.The probability reliability and reliability index of masonty gravity dam are obtained in the result of calculation program.The results demonstrate that based on Matlab the calculation accuracy is higher and the process is faster.
