摘要
针对墩柱节段之间的接缝设置,选取4种不同构造形式的预制节段拼装桥墩进行模拟分析,在ABAQUS软件中实现了接缝处的接触模拟.分别对局部接口处有无现浇混凝土、是否含有耗能钢筋4种不同构造的预制桥墩进行拟静力的循环往复模拟加载,得到预制桥墩的力-位移的滞回曲线,通过分析滞回曲线的各项参数,得到了局部现浇混凝土和耗能钢筋对预制节段拼装桥墩刚度和耗能能力的影响.
Aiming at the joint setting between piers and columns,4kinds of precast segmental assembly piers with different structural forms are simulated and analyzed.Contact simulation at the seams is simulated in the software ABAQUS.The4kinds of prefabricated piers of different structures are subjected to pseudo static cyclic simulation loading whether it has on-site concrete or energy-dissipating bars on local interface.The hysteretic curve of force-displacement of precast pier is obtained.The influence of local cast-in-place concrete and energy-dissipating bars in precast segmental assembly piers stiffness and energy dissipation capacity is obtained by analyzing the parameters of the hysteretic curve.
