| 摘 要： | 基于钢筋锈蚀引起砼开裂机理,考虑钢筋锈胀引起砼结构失效具有明显的模糊性,将模糊概率的数学模型引入锈蚀砼结构的可靠度分析中.对砼因钢筋锈胀开裂引起的耐久性失效进行模糊可靠度分析,建立钢筋锈蚀后耐久性模糊可靠度分析模型.通过算例证明,该方法符合实际情况,可用于工程实践.

| Abstract: | Based on the mechanism of concrete cracking due to steel bar corrosion,and the fuzzy property of structure failure caused by corrosion cracks,the mathematic model of fuzzy probability is introduced into the reliability analysis of concrete with corroded steel bar.An example calculating the probability of concert durability failure is given,indicating the feasibility of this method. |
