摘要

为明确连接刚度对调频型颗粒阻尼器(Tuned Particle Damper,简记为TPD)减震控制效果的影响,确定实际可用的较优的阻尼器连接刚度范围,本文设计制作了某钢筋混凝土框架结构1:30缩尺试验模型及可用于该试验模型的调频型颗粒阻尼器,设计了不同的TPD连接刚度,通过系列振动台试验研究了连接刚度对该型阻尼器减震控制效果的影响。结果表明:合理设计的TPD能有效降低地震荷载作用下结构的位移响应;TPD与受控结构的连接刚度对TPD减震控制效果影响显著,TPD自振频率与结构控制方向基频之比在0.90~1.10范围内,TPD减震效果较优。

Abstract

In order to clarify influences of connected rigidity on damping effects of tuned particle dampers (TPDs) and determine the available optimal range of the connected rigidity between TPD and a structure, a 1/30-scale RC frame model was designed and manufactured, TPDs with various connected rigidities were designed to reduce vibrations of the test model, influences of connected rigidity on TPD’s vibration control effect was analyzed through a series of shaking table tests. The results showed that the TPDs properly designed can reduce structural displacement responses effectively; the connected rigidity between TPD and the controlled structure has obvious influences on the TPD vibration control effect; when the ratio of the TPD’s natural frequency to the structure’s fundamental frequency in the controlled direction is within a range of 0.90 to 1.10, the TPD’s vibration control effect is better.
