Abstract

Abstract

The axial compression tests on six CFST columns reinforced by GFRP and one contrast specimen of CFST column are done in this article, to research the mechanical behavior of this composite member.Experimental results indicate that, the confinement with filament wound reinforced steel tube can greatly enhance the bearing capacity of composite columns.The carrying capacity of the GFRP strengthened CFST column with 90 and 45 fiber orientation can be raised by 40.9% and 27.3% as compared with CFST column.The mechanical performance of composite columns is also discussed in this paper, and the formula of ultimate bearing capacity and simplified model of stress-strain relation of the composite column have been proposed, whose results are in good agreement with the test results.
