带TLD多层隔震结构的抗震混合控制研究

Research on Seismic Control of Multistoried Building with TLD and Base-isolation Bearing

为进一步减少隔震结构的地震响应,提出调谐液体阻尼器(TLD)与隔震系统联合控制的方法。基于集中质量模型推导出TLD与隔震层联合作用下多层剪切型结构的耦联运动方程,并结合算例进行中震作用下的时程分析。计算结果表明:在设置了隔震层的多层结构体系的顶层增设TLD系统可有效减少主体结构及隔震层的地震位移响应。

In order to further reduce the seismic response of base isolation structure,a new seismic control method was proposed,that is control by TLD and isolation bearing.Based on the lumped mass model,the motion equation of the multi story shear type structure with the combined action of the base isolation layer and TLD was derived,and the numerical calculation of time history response analysis is carried out.The calculation results show that setting TLD system on the top layer can effectively reduce the displacement response of the structure with the base isolation layer under earthquake.
