中文摘要：

基于黏滞阻尼器的耗能原理，针对地震时阻尼器位移小的特点，提出一种可提高阻尼器耗能能力的位移放大装置，并在此基础上设计出一种黏滞阻尼墙。针对黏滞阻尼器力学模型，增设放大装置后，得到带放大系数的黏滞阻尼墙力学模型。以12层框架为例，利用有限元软件分析比较带放大装置的黏滞阻尼墙减震结构与常规阻尼器建筑结构的减震效率。在加速度、层间位移、层间剪力等地震响应的控制效果方面，基于文中提案采用放大装置的减震结构更为有效。

英文摘要：

A new viscous damper was proposed to improve energy dissipation abilitity in this paper.It was de-signed based on the viscous damper’s energy dissipation principle with the consideration of small displace-ments of traditional dampers.A displacement amplification device was added in this new viscous damper.Tak-ing the 12-story frame structure as an example,structural responses with the installation of normal dampers and the new viscous damper were obtained by using the finite element modeling.Results show that the accelera-tion,story drift and inter-story shears of the structure with new damper are reduced more significantly.
