摘要

摘要: 对新型GFRP-钢复合筋进行拉伸性能测试，分析了复合筋的破坏过程和力学性能指标。同时构建了新型GFRP-钢复合筋的应力-应变关系理论模型，并将其与试验结果进行对比分析。结果表明： GFRP-钢复合筋的应力-应变曲线表现出明显的双线性特征，其在内芯钢筋屈服后仍具备稳定的抗变形能力，所建立的应力-应变关系理论模型与试验结果吻合较好，证明了该模型能够有效地反映复合筋的拉伸性能。

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.
