摘　　要：在试验研究基础上,利用有限元软件ABAQUS,选取碳纤维增强材料CFRP、聚氯乙烯PVC管、钢筋及混凝土合理的本构关系,对有限元模型单元进行网格划分,将边界条件和荷载施加到有限元模型上,选择合适加载方式、定义收敛准则,建立PVC-FRP管钢筋混凝土柱有限元分析模型,并验证该分析模型的正确性。利用该模型分析偏压PVC-FRP管钢筋混凝土柱的受力性能,揭示FRP条带、PVC管和混凝土在受荷过程中的工作机理。Based on the experimental study, using the finite element software ABAQUS, the reasonable constitutive relations of CFRP strips, PVC tube, steel and concrete were chosen, the mesh of finite element model was divided, the boundary condition and load were applied to finite element model, the reasonable loading mode was chosen, the convergence criteria was defined.The finite element analysis model of PVC-FRP confined reinforced concrete column was established and then verified.The mechanical behavior of PVC-FRP confined reinforced concrete columns was analyzed by using the model, and the working mechanism of FRP strips, PVC tube and concrete were revealed.
