The results show ed that the impro ed stress-strain model for confined core concrete is fitting for the simulation of bearing capacity and peak strain. The post-peak response show s a good agreement w ith the test results before high distortion, but the subsequent deformation doesn. t accord w ith the true state. So ANSYS can be employed to analyze steel tube filled w ith steel reinforced high-strength concrete.
