| 摘 要： | 根据隔震技术在大跨空间结构中的研究现状,针对现有摩擦摆支座不具有抗拔性能的缺点,基于竖向抗拔摩擦摆支座的专利设计,提出一种新型构造的竖向抗拔摩擦摆支座,对其进行构造设计,建立相应的理论模型,并对相关力学性能进行试验研究。试验内容包括测定竖向抗拔摩擦摆支座在简谐激励下的滞回性能;考察竖向压力和滑移速度对支座滞回性能的影响;测定竖向抗拔摩擦摆支座滑动面间的摩擦系数以及竖向压力和滑移速度对摩擦系数的影响。试验结果表明,支座具有良好的耗能能力。

| Abstract: | This thesis,in concern with the seismic isolation technology in long span structures,focuses on the research of bearing.In allusion to the defect of,it designs a new type vertical resisting pulling friction pendulum bearing.The mechanical properties test of the bearings is carried out on hydraulic servo tester.The loading capability and dynamic characteristics tests of the proposed FPB-3000 were carried out.Some key parameters,such as vertical pressure,horizontal sliding velocity,which affect on the performance of seismic isolation,are studied.It is shown that the proposed bearings possess good performance. |
