设计验算点新方法的应用及物理意义

The Application and Physical Meaning of the Design Checking Point New Method

通过对结构可靠度的理论研究,具体分析了目前成熟的结构点可靠度的计算方法,进而设计验算点法克服了中心点法的缺点,其具有不易发散,收敛速度快和计算结果精度高的特点。根据设计验算点法的几何意义与数学分析,得出在工程实际中的物理意义,使此种方法在解决结构可靠度分析问题中具有很大的实用性。

Based on the structural reliability theory, the paper analyzes the mature structure reliability calculation method and the design calculation point method overcomes the Shortcomings of center point method, it has the characteristics including not easy to divergence, fast convergence speed and high calculation accuracy. According to the design calculation point method of the geometric significance and mathematical analysis, we obtains the physical meaning in the actual engineering, so that such method has the great practicability in solving problems about the structural reliability analysis.
