高层建筑利用悬吊质量摆的减震研究

SEISMIC RESPONSE REDUCTION FOR TALL BUILDINGS BY SUSPENDED MASS PENDULUMS

本文研究了高层建筑利用悬吊质量摆的减震作用,首次提出了利用摆减小高层建筑多个振型反应的方法。文中给出了具有不同悬吊方式的摆一高层建筑结构体系的力学模型及振动方程利用数值分析方法探讨了摆的不同悬吊方式及摆与结构的质量比等因素对结构地震反应的影响,给出了对于实际工程应用具有参考意义的结果。

In this paper the reduction effects on the seismic response of tall building are investigated by applying the suspended mass pendulums and the approach of reducing multi modal responses of tall building using this device is presented. The mechanical models and equations of motion for tall buildings with the different suspended way pendulums are given and then the effects of different suspension way of pendulums and ratio of the pendulum and structure masss on the structural seismic responses are studied by employing the numerical analysis. Finally some conclusions with practical engineering significance are gotten.
