摘要
钢筋混凝土连续板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。采用串联分析模型 ,计算结构体系的失效概率。即结构体系中有一个构件失效 ,则整个结构体系失效。连续板的失效概率应为荷载出现概率和相应荷载作用下的失效概率乘积的总和。以此对结构的安全性进行评估 。
Being used for many years, the existing concrete continuous slab differs from functional design in performance and load-appearance. This paper presents the series analytic model to calculate structural failure probability. It is that the whole structural system should fail only if one of the structural members fails. The failure probability of the continuous slab is the sum of the product of load-appearance probability and the failure probability under the action of the corresponding load. Therefore, we can assess the safety of the structure and provide a theoretical basis for maintenance of existing industrial mill building.
