摘要
现有预应力混凝土结构在预应力筋脱钝后 ,是否发生耐久性失效还取决于结构所处的环境条件。通过分析各主要因素对预应力混凝土结构耐久性的影响程度 ,确立了各主要影响因素的模糊特征函数 ,并基于它们之间的逻辑关系模型 。
After the depassivation of steel bars of existing prestressed structures,whether the durability failure may occur or not depends on the exposure conditions where the structures are located.Through analyzing the main factors,which affect the durability of prestressed concrete structures,the fuzzy characteristic functions of the main affecting factors are built.Based on the logical relation model between these factors,the durability evaluation method on the existing prestressed concrete structures is submitted.
