装配整体式地铁车站侧墙底节点抗震性能研究
|
摘要
为了评价装配整体式地铁车站整体抗震性能,以北京金安桥装配整体式地铁车站为背景,设计制作了一个足尺预制拼装侧墙底节点和一个作为对比的足尺现浇侧墙底节点。采用低周循环加载试验,研究了预制拼装侧墙底节点的破坏形态、滞回特性、承载力、变形能力、耗能性能以及套筒灌浆连接接头受力状态等指标。试验结果表明:预制拼装侧墙底节点与现浇侧墙底节点的承载力和变形能力基本相当,但耗能性能显著降低;两者的破坏形态明显不同,现浇侧墙底节点的裂缝发展比较充分,分布均匀密集,而预制拼装侧墙底节点的裂缝相对集中,其主要分布在刚度突变处以及弯矩最大截面。与现浇侧墙底节点相比,预制拼装侧墙底节点的初始刚度较大,但加载后期,其刚度显著降低。另外,基于灌浆套筒接头在构件中的受力状态分析,对灌浆套筒提出了一种等效抗弯刚度简化处理方法并对两种不同连接方式的侧墙底节点进行了数值分析,其破坏形态和骨架曲线与试验结果吻合较好,验证了该方法的合理性。
In order to evaluate the seismic behavior and performance of the assembled monolithic subway station,a fullscale precast concrete sidewall joint and a full-scale cast-in-place concrete sidewall joint were designed based on the Beijing Jin'anqiao subway station. The important indexes were studied under low-cycle repeated loading,such as failure modes,hysteretic characteristics,load-bearing capacity,deformation capacity,energy dissipation capacity and forced state of grout sleeve splicing et al. The results showed that the deformation capacity and load-bearing capacity of the sidewall joints were approximately same. The energy dissipation capacity of precast concrete joint was much lower than that of the cast-in-place concrete joint,and the crack failure modes were different obviously. The crack distribution of the cast-in-place concrete joint was homogeneous,but that of the precast concrete joint were centralized. For the precast concrete joint,the main cracks were distributed around the sections with stiffness mutation or maximum moments. The initial stiffness of the precast concrete joint was larger than that of the cast-in-place concrete joint in the prime loading stage,but it decreased drastically in the later loading stage. Based on the experimental results,the grouting sleeves were simplified by the principle basis of equivalent flexural rigidity,and the sidewall joints were simulated. The experimental results agree well with the those of numerical analysis,which validates the rationalization of the proposed method.
