Abstract
Based on the existing fiber reinforced polymer (FRP) durability research, considering the difference different regions, a multi-factor durability evaluation model for structural reinforcement FRP has been established. Firstly, combined with the result of rapid aging experiments, a benchmark aging model of a single factor is built. Secondly, classifying the various factors according to different geographical environments, and taking the difference between various environmental factors and test conditions into count, the benchmark aging model is revised. Thirdly, it is to make sure the main environmental factors, determine the effect weight of various factors in different areas and a coupling aging model is established through the coupled superposed. Finally, the carbon fiber reinforced polymer (CFRP) coupling aging model is obtained and compared with actual environmental in A area as an example to validate the model. The result that it can ascertain both trends are consistent and be used to guide durable design.
