中文摘要: |
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,衫,给出了算例分析。 |
英文摘要: |
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. |
