摘　　要：为研究CFRP筋混凝土柱在低周反复荷载作用下的骨架曲线,基于已有的3根CFRP筋混凝土柱的滞回曲线,采用混凝土损伤塑性本构模型和碳纤维筋本构模型,运用有限元分析软件ABAQUS对其试验过程进行数值模拟,并将模拟所得骨架曲线与试验结果进行对比。结果表明:通过数值模拟得到的骨架曲线与试验结果吻合较好,数值模拟趋势与试验得到的趋势一致,从而对该有限元模型的适用性进行了验证。To study the skeleton curve of concrete columns reinforced with CFRP bars under cyclical loading, based on hyster- esis curves of three concrete columns reinforced with CFRP bars, a concrete damaged plasticity model and a simple CFRP constitu- tive model are established, and numerical simulation is carried out with ABAQUS finite element software. Comparison of the numeri- cal results and the test results is done, and the results show that simulation results are in good agreement with the experiment ones. The trends of the numerical simulation show a qualitative agreement with the experiment ones. It can be proved that the finite ele- ment model is suitable for the analysis of concrete columns reinforced with CFRP bars.
