中文摘要：

提出了一种由放大杠杆并联附加在黏滞阻尼墙中的位移放大装置,并对设置位移放大型阻尼墙的新型减震结构进行理论和振动台试验研究。对附加位移放大装置的黏滞阻尼墙系统（AVDW）进行理论分析,给出了基于杠杆倍数的AVDW阻尼力的放大理论计算公式。通过对传统阻尼墙减震结构及2种放大倍数AVDW减震结构的3层模型进行不同加速度峰值输入的振动台试验研究,试验结果表明新型AVDW减震结构减震效果显著。最后通过对一12层框架结构进行传统阻尼墙减震结构及附加AVDW的新型减震结构的数值分析对比,结果表明AVDW相对于一般阻尼墙结构,能更有效地减小结构的层间位移、层间剪力、层加速度等结构动力响应。

英文摘要：

In this paper,a displacement amplification device composed of several levers in parallel connecting with a viscous damping wall is proposed.And the dynamic tests and numerical analysis of new energy dissipated structures with displacement amplification dampers are performed.The theoretical analysis on AVDW is given to obtain the formula of the damping force based on lever magnification.Shake table testing with different acceleration peak inputs of a 3-story model structure is used to demonstrate the traditional damped and the new damped structure with two kinds of magnification.Experimental results show that the new energy dissipated structures with AVDW have remarkable effects.The traditional damped and the new damped structure with AVDW based on a 12-story structure model are simulated numerically at last.The numerical analysis results indicate that AVDW yields significant reduction in the drift,the shear force and the acceleration response of structure compared with traditional damping wall system.
