摘要
针对纤维增强聚合物(FRP)筋体,综合分析了水溶液浸泡、盐溶液侵蚀,酸溶液和碱溶液,以及冻融等不同作用介质和作用方式下筋体的拉伸性能,归纳总结了FRP筋体拉伸强度演化规律。从FRP筋拉伸强度退化作用机理出发,以Arrhenius方程为基础,探讨了不同作用方式下FRP筋拉伸强度寿命预测模型方程的参数特征。
The durability of FRP in different corrosive environment has been widely concerned and studied.In this paper,the tensile properties of FRP bars such as aqueous solution immersion,salt solution erosion,acid solution,alkali solution,and freeze-thaw were analyzed comprehensively under different action media and modes,and their evolution law of tensile strength was summarized.Based on the degradation mechanism of tensile strength of FRP bars and the Arrhenius equation,the parameter characteristics of the prediction model and equation for the tensile strength life of FRP bars under different action modes were discussed.
