摘要
首先对一座安装有拟粘滞摩擦耗能器的1：8的16层三跨钢结构模型、该结构未装耗能器的空框架以及装有普遍支撑的框架模型进行了振动台地震模拟试验和动力特性试验，试验结果表明拟粘滞摩擦耗能器有良好的减振效果．然后对影响耗能体系减振效果的主要参数进行了数值研究，讨论了支撑刚度、初始起滑力和耗能器接触刚度对减振效果的影响．
Firstly, this paper describes the earthquake simulation testing of a 16-story structure with pseuco-viscous energy dissipators (PVEDORs), with ordinary braces,of without any braas. The testing results show that PVEDORs have a good vibration-suppressing effects. Then, parameter.influence of PVEDORs on suppressive effectiveness of strcutural vibration under earthquake is studied. These parameters include brace stiffness, initial slip load and contact stimness of PVEDORs.
