摘要:
柱端铰型受控摇摆钢筋混凝土框架采用整体结构刚度"弱化"的方式来减小结构的地震作用效应,同时通过设置层间阻尼器来控制结构地震位移响应并消耗地震能量。模拟地震振动台试验研究结果表明,在罕遇地震作用下,模型主体结构未见损伤,结构抗震性能优异。首先介绍柱端铰型受控摇摆钢筋混凝土框架结构形式,并进行有限元计算分析,通过与试验结果对比验证数值建模的正确性,其次使用Pushover分析方法对比和评定无控及受控状态下柱端铰型摇摆框架的抗震性能。分析结果表明,通过设置层间耗能阻尼器,受控柱端铰型摇摆框架的位移响应可以得到有效控制,地震加速度和位移响应满足抗震性能指标。
Abstract:
Controlled Rocking Reinforced Concrete Frame with Column-end-hinge joints (CR-RCFC) has less seismic effect due to its weakened lateral-resisting stiffness and installs inter-story dampers to control the earthquake displacement response, dissipate the earthquake energy. Shaking table test research indicates that CR-RCFC has excellent seismic performance and its main body would not be damaged under rare earthquake. Firstly, configuration of CR-RCFC is introduced and numerical modelling of CR-RCFC is verified by comparing with the experimental result. Secondly, the seismic behavior of CR-RCFC structure with and without dampers are compared and evaluated by Pushover analysis method. Analysis results show dampers can effectively control the displacement response of CR-RCFC, both earthquake acceleration and displacement responses meet the seismic performance requirements.
