摘要

摘要: 将概率计算、递推公式和数值分析相结合的结构连续变更方法用于刚架结构的可靠性分析，实现了结构内力和极限状态函数的连续生成，计算了结构总体失效概率。简化了繁琐的总刚运算，避免了结构重分析，为结构退化为机构提供了新的判断依据。加快了系统失效模式的搜索速度，并进一步提高了结构系统的可靠性分析时效，为结构系统可靠性分析理论的发展提供了新思路。

Abstract: The theorem of structural continual variation was used to analyze reliability of frame structure. The method was combined with probability analysis and numerical calculus and recurrence formula and branch- and- bound method to evaluate the system. Continually assembling global stiffness matrix and repeatedly inverse matrix operating are avoided in the new method. A new criterion of system failure is introduced. The time- effect of the reliability analysis is further increased. The new idea of the development of the theory of the system reliability analysis is provided.
