采用变阻尼式TMD的钢框架结构振动台试验
|
摘要
提出了一种新型变阻尼式调谐质量阻尼器(TMD),并将该阻尼器安装在两层单跨的钢框架模型结构上.通过对比无控状态、传统TMD控制状态、变阻尼式TMD控制状态下钢框架结构的动力响应,分析了变阻尼式TMD在Kobe波、Taft波和兰州波激励下的减震控制效果.试验结果表明:变阻尼式TMD可降低结构的自振频率并延长周期,采用变阻尼式TMD减震装置后,加速度响应最大可降低41.32%,位移响应最大可降低62.07%,最大减震效果较传统TMD提高了9%,且随着地震动峰值的增加,减震装置的控制效果越显著.
A new type of tunded mass damper(TMD) with variable damping was presented and installed on the steel frame model structure of the two-layer single span.Through the comparison of dynamic response of steel frame structure under the condition of uncontrolled state,traditional TMD control state and variable damping TMD control state,the control effect of variable damping TMD control was studied under the excitation of Kobe wave, Taft wave and Lanzhou wave. The results show that the variable damping type TMD can reduce the vibration frequency of the structure and prolong the vibration period of the structure.With the variable damping TMD damper,the acceleration response can be reduced by up to 41.32%,the displacement response can be reduced by up to 62.07%.Compared with conventional TMD,the maximum damping effect is improved 9%,and with the increase of the peak of ground motion,the control effect of the damping device is more obvious.
