摘要
现役建筑结构经过一段时间的使用,其抗力和荷载效应都与设计时的不同。本文根据实际情况,采用串联分析模型,计算结构体系的失效概率。并通过对结构体系的失效概率直接进行调整,实现对现役结构可靠度的维修设计。以此对结构的安全性进行评估,为框架结构的维修决策提供了依据。
Being used for many years, the existing structure differs from original design in performance and load-appearance. According to the realities, this paper presents the method of serial connection analysis to calculate structural collapse probability. We achieve the maintenance design for existing structural reliability by direct adjusting the failure probability of a structural system. Therefore, we can assess the safety of the structure and provide a theoretical basis for maintenance of existing frame structure.
