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。

Abstrac t: RC tube in a tube structure with fric tion joints is designed to control the seismic response of the RC tube
in the tube structure. The frame tube and the wall tube are connec ted by the fric tion joints. Under seve re earth2
quake s, the differential movement be tween the frame tube and the wall tube causes hysteretic energy dissipation by
the friction joints slipp ing. Nonlinea r time2history dynamic analysis has been used to study and to demonstrate the
se ism ic pe rformance of the RC tube in the tube structure with friction joints.
Key wor ds: tube in tube structure; fric tion joints; hysteretic energy dissipa tion
