摘要: 为探究预应力碳纤维筋型钢混凝土偏拉柱荷载-位移曲线与延性的影响因素并精确模拟其荷载-位移曲线的变化趋势,对7根不同加载偏心距与张拉水平的预应力碳纤维筋型钢混凝土柱进行偏心受拉试验,在试验的基础上建立预应力碳纤维筋型钢混凝土偏拉柱荷载-位移计算模型,并将计算结果与试验结果进行对比。结果表明:加载偏心距与预应力张拉水平为试件荷载-位移曲线及其延性的重要影响因素;荷载-位移计算模型计算值与试验值二者吻合较好,表明此种模型能较好地反映预应力碳纤维筋型钢混凝土偏拉柱的受力和变形过程。

Abstract: In order to explore the influence factors of load displacement curve and ductility of prestressed carbon fiber reinforced steel reinforced concrete eccentric columns and accurately simulate the change trend of load displacement curve, seven prestressed carbon fiber reinforced steel reinforced concrete columns with different load eccentricity and tension level were tested in eccentric tension, and the load displacement of prestressed carbon fiber reinforced steel reinforced concrete eccentric columns was established on the basis of the test. The model is calculated and the calculated results are compared with the test results. The results show that the load eccentricity and the prestressed tension level are the important factors affecting the load displacement curve and ductility of the specimen, and the calculated value of the load displacement model is in good agreement with the test value, which shows that the model can better reflect the stress and deformation process of the prestressed carbon fiber reinforced steel reinforced concrete eccentric tension column.

Key words: prestressed CFRP reinforcement, steel reinforced concrete column, load calculation model, composites
