摘要

针对阻尼连体结构,采用串并联质点系层模型,沿连体设置方向施加El Centro1940地震波,讨论了毗邻结构自振周期比与连接体阻尼刚度变化对阻尼连体结构地震响应的影响。研究结果表明:毗邻结构自振周期比与连体阻尼刚度对结构的地震响应影响较大,存在一个使结构地震响应为最优的周期比与阻尼刚度值,为实际工程应用和研究提供一些参考。
Aimed to damping connective structure,using series-parallel particles layer model,along the connected-building direction put the El Centro1940 seismic wave for the structure,the influence on seismic response is discussed while the natural vibration period ratio of adjacent structures and damping stiffness of connective structure are changed.Research results show that the natural vibration period ratio of adjacent structures and damping stiffness of connective structure have a greater impact for the seismic response of the damping connective structure,on the other hand,there is a period ratios and damping stiffness which make the seismic response to optimal.The result provide some reference to the practical application and research.
