Abstract

Abstract

Tensile tests were conducted on a new type of GFRP-steel composite bars, the failure process and mechanical performance indicators of the composite bars were analyzed. A theoretical model of stress-strain relations for the new type of GFRP-steel composite bars was constructed, and compared with the test results for analysis. The results showed that the stress-strain curves of the GFRP-steel composite bars exhibited obvious bilinear characteristics, and it still maintained a stable deformation resistance after the yielding of the inner core steel rebars. Furthermore, the theoretical model of stress-strain relations established in the paper matched well with the test results, demonstrating the effectiveness of the model in reflecting the tensile properties of the composite bars.
