| 摘 要： | 针对隔震结构在地震作用下隔震层位移较大,可能会与相邻非隔震结构之间产生碰撞问题进行了分析,采用简化模型对隔震与相邻非隔震结构之间布置粘滞阻尼器的减震控制的工作机理进行了研究。建立了隔震与相邻非隔震结构之间布置粘滞阻尼器减震控制的数值仿真分析模型,研究了粘滞阻尼器的阻尼系数、布置位置以及隔震结构隔震层刚度对结构顶点位移的影响。结果表明:随着阻尼器阻尼系数和隔震结构隔震层刚度的增加,隔震结构顶层位移也随之增大,阻尼器布置位置越靠近隔震层,相邻非隔震结构顶层位移控制效果越明显。

| Abstract: | The problem of the base-isolated structure which is possible to pound adjacent buildings on account of the large horizontal displacement of isolated story is analyzed.The mechanism of the linking viscous dampers connecting base-isolated structure with adjacent building is studied with simplified model.The numerical analysis model of the linking viscous dampers connecting base-isolated structure with adjacent building is built to research the influence on the change of damping coefficient,distributing of damper and stiffness of isolated story.The results show that the top displacement of the isolated structure increases with damping coefficient of the viscous damper and stiffness of isolated story.The shorter the distance between the installed position and isolated story of the damper is,the better the control effect of the top displacement of the adjacent general structure will get. |
