Abstract

Through the CFRP anchor bond performance test after acid,alkali,salt,freeze-thaw cycle environmental impact,fitting different environment bond-slip relational expression and also based on the test parameters,CFRP anchor bond unit was simulated with nonlinear spring element Combin 39 of ANSYS．The fit -s curve was used for determining F-S relation parameters of the spring unit．The comparison between the simulation analysis and experimental results showed that the fit bond-slip relation curve could reflect well the CFRP reinforcement and epoxy mortar performance changes after acid,alkali,salt,freeze-thaw cycle environmental impact．Which provided a theoretical basis for performance analysis,design theory and engineering application of CFRP anchor under special environment,also provided a reference for compiling and perfecting relevant norms．
