摘要：基于离心预制混凝土组合柱抗震性能试验，采用ABAQUS软件对该类型组合柱在轴压及水平往复荷载作用下的受力性能进行了非线性有限元分析，研究了轴压比、预制管及芯部混凝土强度、体积配箍率和预制管空心率对柱承载力及变形能力的影响。并采用拟合法建立了适用于该类型组合柱的恢复力模型。研究结果表明：有限元结果与试验结果吻合较好，在轴压及水平往复荷载作用下，柱的破坏模式为压弯破坏，耗能能力较好。柱承载力随轴压比增加而提高，但变形能力降低，当轴压比超过临界值时，柱的受力状态转为小偏心受压，承载力降低；提高预制管或芯部混凝土强度可提高柱承载力，但会降低柱的变形性能；提高体积配箍率及降低预制管空心率可改善柱的变形能力，当空心率降低至20%后，其影响可忽略。本文所建立的恢复力模型与试验结果吻合较好，能够较为准确地模拟该类型组合柱的滞回特性。

Finite element analysis on seismic behavior and research on restoring force model of concrete-filled centrifugal precast concrete tube columns
Abstract: Based on experimental on seismic behavior of concrete-filled centrifugal precast concrete tube columns, the nonlinear finite element analysis of mechanical behaviors of the columns under axial compression loads and lateral cyclic loads was carried out by using ABAQUS software. The influences of axial compression ratio, the strengths of the precast tube and core concrete, volume ratio of transverse stirrups and hollow ratio of the precast tube on the bearing and deformation capacity of the columns were studied. The restoring force model of the columns was established by fitting method. The results show that the results of finite element simulations are in good agreement with that of the test. The failure modes of the columns under axial compression and lateral cyclic loads are compressed-flexural failure, with a good energy dissipation performance. The bearing capacity of the columns is enhanced with the increase of axial compression ratio, while deformation capacity deteriorates, when axial compression ratio exceeds the limit value, the bearing capacity decreases because the stress state of the column changes to small eccentric compression. The bearing capacity can be enhanced by improving the strengths of the precast tube or core concrete, but it has a negative effect on the deformation capacity of the columns. Increasing the volume ratio of transverse stirrups and decreasing the hollow ratio of the precast tube can improve the deformation capacity of the columns, but when the hollow ratio is reduced to 20%, the effect can be neglected. The established restoring force model is in good agreement with the experimental results, which can accurately simulate the hysteretic behavior of this type of composite columns.
