采用颗粒调谐质量阻尼器的钢框架结构振动台试验研究
Shaking table test of steel frame structure with particle tuned mass damper
摘要
Abstract
Shaking table tests of a five-story steel frame with/without particle tuned mass dampers were carried out to study the damping effect under the actual seismic wave and Shanghai artificial wave excitation.The influence of dampers parameters on the damping effect was analyzed by adjusting the parameters of different suspension length (frequency ratio),mass ratio,and gap clearance from particle to the container wall.Experimental results show that the new dampers can achieve good damping effect under different earthquake action,especially under Shanghai artificial wave;for multi-story steel frame structure,it can effectively control the first mode of vibration,but the control effect for higher modes is variable;the new dampers can achieve optimal damping effect when the frequency of the damper is the same as the fundamental frequency of the main structure,and can still have certain effects when the frequency of the damper is not the same as the fundamental frequency of the main structure,indicating its robustness;with a suitable mass ratio (0.66％),particle tuned mass damper can achieve the best damping effect;when the gap clearance between the particle and the container is 1.6D ～ 3.6D,the damper can achieve the best damping effect while keep small damper response.关键词
