摘要
围绕结构构件的可靠度问题,介绍了结构可靠度的基本概念,采用目前进行可靠度分析最常用的方法JC法,根据可靠指标的定义,从可靠指标的几何意义出发,将求解可靠度问题转化为求解有约束条件的极小值问题,通过非线性规划软件L ingo实现对结构构件可靠指标的计算。
The basic concept of structure reliability is introduced bases on the structure reliability of structure members. Adopting the common used JC method to carry out structure reliability, according to the definition of reliability index and based on the geometric meaning of reliability index to turn the solution of reliability to the solution of minimum value with constraint conditions, and realizing calculation of structure member＇s reliability index with nonlinear programming software.
