Abstract: The properties of square steel tube filled with steel reinforced high-strength concrete were analyzed by using finite element analysis software ANSYS. The results showed that the improved stress-strain model for confined core concrete is fitting for the simulation of bearing capacity and peak strain. The post-peak response shows a good agreement with the test results before high distortion, but the subsequent deformation doesn't accord with the true state. So ANSYS can be employed to analyze steel tube filled with steel reinforced high-strength concrete.
