| 摘 要： | 本文在分析结构可靠性第二水平法基础上提出了一个新的结构可靠性半概率分析方法,它是应用最优性条件,直接计算出失效界面上使其到转换空间原点距离最短的设计点,以致得到结构可靠性安全指数。本文将此方法用于结构可靠性分析,给出若干算例并获得此较满意的数值结果。

| Abstract: | A new semi-probabilistic method of structural reliability analysis based on
the method of second level analysis of the structural reliability is introduced in
this paper.The design point on the failure margin from which the distance to
original point in the transform space is the shortest can be immediately found by
using optimality condition,so that the safety index of structural reliability
can be aehieved.Application of this method to structural reliability analysis is
illustrated with examples and the numerical results obtained are satisfactory. |
