中文摘要：

通过一四层无粘结预应力现浇混凝土空心板柱结构的1/4比例模型的模拟地震振动台试验,对其在弹性和弹塑性阶段的抗震性能以及在EI Centro地震动不同峰值加速度作用下的地震反应和受力过程进行了研究。对无黏结预应力现浇混凝土空心板柱结构的破坏形态、滞回性能、骨架曲线、恢复力模型、延性、刚度退化、耗能能力进行了比较深入的分析。研究结果表明,预应力现浇混凝土平行圆管空心板柱结构具有一定的抗震能力,位移延性良好。

英文摘要：

A 1/4-scale specimen of four-story post-tensionect prestressed concrete hollow slab-column structure was constructed.The parameters in this study included the dynamic behavior of elastic and elastic-plastic stages and the seismic performance of the structure under different peak accelerations of El Centro earthquake ground motion.The failure mechanism,hysteretic behavior,sheleton curces,restoring force model,displacement restoring capacity,ductility,rigidity degeneration and energy dissipation of post-tensioned prestressed concrete hollow slab-column structure were studied systematically.The results indicate that the structure performs well under seismic conditions;better ductility as a whole.
