摘要
基于可靠指标的几何涵义 ,采用遗传算法 (GA)计算公路桥梁结构工程的可靠度 ,并期望能够在有限的模拟次数中达到精度要求 ,同时给出可靠指标和设计验算点 ,以适应公路桥梁结构工程中功能函数高次非线性和复杂性的情况。最后通过算例证明该法能很好地求出全局最优解。
Based on the geometric implication of reliability index,genetic algorithm (GA) is used to calculate the reliability of highway bridge structural engineering with an expectation of meeting the accuracy requirement in a limited number of analogue times. Meanwhile, the reliability index and the design calculation verification point are given to suit the high order nonlinearity and complexity of the functions of highway bridge structural engineering.Finally, it is illustrated by a case calculation that an overall best solution can be found by this method.
