摘要： 运用有限元软件ABAQUS建立了圆柱桥墩非线性有限元模型,采用循环往复加载的Pushover方法模拟圆柱桥墩包括保护层及核心区混凝土、箍筋和钢筋的破坏过程,研究轴压比对圆柱桥墩延性破坏的影响。研究表明,核心区混凝土的破坏时间随着轴压比的增大而缩短;轴压比的变化对圆柱桥墩的保护层混凝土、纵筋首次屈服时间的影响无明显规律可循;一定范围内,位移延性系数随轴压比的增大而减小,表明适当的轴压比能够提高桥墩的抗倒塌能力;圆柱墩的滞回耗能能力也随轴压比的增大而减小。

关键词: 轴压比, 延性, 圆柱桥墩, 循环往复Pushover, 屈服荷载

Abstract: Nonlinear FE models of cylindrical bridge piers were established using ABAQUS. Failure process of cylindrical bridge piers including protective layer, core area concrete, stirrups and longitudinal reinforcement were simulated using Pushover analysis with cycle loading. The effects of axial compression ratio on ductility failure of cylindrical bridge piers were studied. Numerical results showed that the failure time of core area concrete was shortened with increasing of axial compression ratio. While first yield time of protective layer and core area concrete, stirrups and longitudinal reinforcement had no significant impact rules to follow. Within certain range, displacement ductility coefficient decreased with increasing of axial compression ratio, which showed that proper axial compression ratio would improve ductility seismic ability of bridge piers. Results also showed that cylindrical piers hysteretic energy capacity increased with the axial compression ratio decreases.

Key words: Pushover analysis with cycle loading, ductile, cylindrical piers, axial compression ratio, yield load
