Based on the high-strength concrete column confined by CFRP under sustained load tests, the whole process was non-linearly simulated with ANSYS.Various design parameters such as the number of CFRP layers and different sustained load are considered.Based on the analysis of finite element, the distribution of axial stress of concrete、stress distribution of CFRP and strain distribution of CFRP along longitude are given.The calculated ultimate bearing capacity and strain were corresponding well with experimental results.It indicated that the ultimate bearing capacity and ductility of high-strength concrete columns confined by CFRP under sustained load raise at different levels.Comparing with the non-sustained load specimen, the ultimate stress of the specimen under sustained load still has a little increment as the sustained load goes up when the number of CFRP layers is the same, but the ultimate strain declines with worse ductility at the same time.
