摘要

提出利用筒中筒结构内筒和外筒的相对运动带动耗能装置耗能的的筒中筒结构内部摩擦连接消能减震体系。该体系将结构的内筒和框筒用专门设计的摩擦连接装置连接,罕遇地震下摩擦连接装置滑移产生滞回耗能。文中阐明了该体系的消能减震原理和构造特点,并通过对一栋40层筒中筒结构进行有限元分析,验证了该体系具有良好的抗震性能,可供工程实践参考。
RC tube in a tube structure with friction joints is designed to control the seismic response of the RC tube in the tube structure.The frame tube and the wall tube are connected by the friction joints.Under severe earthquakes,the differential movement between the frame tube and the wall tube causes hysteretic energy dissipation by the friction joints slipping.Nonlinear time-history dynamic analysis has been used to study and to demonstrate the seismic performance of the RC tube in the tube structure with friction joints.
