建筑结构振动原因及减振措施分析

摘要

通过系统分析建筑结构在人的活动及设备振动等使用荷载的激励下产生振动的成因及危害,指出现行建筑结构抗振设计方法的不足并提出了改进措施,对采用TMD减振技术解决结构振动问题提出了自己的看法,同时对建筑结构振动的远端传递问题进行了分析,提出了建立设备、 结构整体有限元分析的解决方法,为消除结构共振问题提供了系统的解决方案.%After analyzing the causes and harms o building structure vibration generated by human activities and equipment vibration, etc. , the author points out the shortcomings of the existing seismic design methods and puts forward some improvement measures and a view on structural vibration problem treatment using TMD damping technology. On the other hand, the problem of structure vibration remote transmission is analyzed, and a method is proposed for the finite element analysis of equipment and structures, which provides a solution to the problem of structural resonance.
