In order to study the impact of concrete strength on mechanical properties of GFRP-concretesteel tubular composite columns under axial compression,the component compression capability of the four components in C30 and C40 concrete strength was examined by using static test method,and the correctness of the model of the Ansys software was also verified. The finite element model of three kinds of concrete strength was established,and the finite element analysis of nine components was carried out.The results showed that with the improvement of concrete strength grade,the limit displacement and the ductility of the specimens were significantly increased,and the ultimate bearing capacity of the specimen was improved significantly.
