摘要
本文用非概率的凸集模型模拟结构的不确定性。将结构的不确定参数描述为区间变量。基于区间分析 ,提出了一种新的非概率可靠性度量体系及分析方法。从物理、几何意义等方面解释了文中理论的合理性。其计算方法简便、实用。
In this paper,the uncertain parameters of structures are expressed by non\|probabilistic interval variables. Based on interval arithmetic, a non\|probabilistic measure and analysis methodology for structural reliability computpation is presented. The measure index of the non\|probabilistic reliability developed here has a clear meaning in physics and geometry. The rationality and feasibility of the proposed theory is explained. Examples of practical application are given.
