| Abstract: | A nonlinear finite element(FE) model was developed to simulate circular concrete-filled stainless steel tubular columns under axial compression,based on the nonlinear material behaviour,nonlinear geometric behaviour and bonding-slip between stainless steel tube and concrete core.The result showed the test result could fit FE results in terms of load versus deformation response.Using the FE model,the load versus deformation curve of the concrete filled stainless steel tubular column was compared with that of... |
