Abstract

Abstract

A finite element analysis(FEA) model for conical concrete-filled double-skin steel tubular stub columns with endplate under axial partial compression was developed and the corresponding tests were conducted.The predicted load versus deformation relationship curves and failure modes were in good agreement with the measured results.The FEA model was then used to investigate the mechanisms of such composite columns further.The stress distribution of each component and the interactions between the concrete and the double-skin steel tubes were analyzed.And then, the main parameters influencing on the load-deformation relationship curves such as taper, strength of the materials, hollow ratio, axial partial compression ratio and rigidity of endplate were investigated.
