This paper introduced the expression of the resistance decreasing with the connection of structures in design and in service and advances a new deterioration model for resistance of existing structures based on .
由于既有结构当前抗力在客观上已知,但人们受知识水平、测量手段的制约而产生认识上的不确定性,其在形式上仍作随机变量处理。
2.
Based on that the density distribution function of technical service life about existing structures obeys blocking tail distribution,a conditional reliability and a hazard rate function of existing structures are established in this paper.
依既有结构的技术使用寿命密度函数服从截尾分布，建立了既有结构的条件可靠度和失效率函数，从期望效益与其望经济风险的优化分析着手，提出了一种既有结构剩余技术寿命的预测方法。

Since the existing structures are existing in reality,their environmental conditions are more clear and definite relative to the structures in design.
结构耐久性设计是针对拟建结构而言的,相对于拟建结构,既有结构已转化为现实的空间实体,环境条件也更为明确,这种根本性的转变使得既有结构的可靠性分析和评定具有其自身的特点,原设计采用的分析模型和参数可能不再适用于既有结构的可靠度分析。
