摘要
为了研究阻尼器在高层建筑中的耗能减震效果,基于ETABS有限元分析程序,采用非线性动力时程分析方法对使用粘滞阻尼器的某高层建筑进行了7度地震作用下结构的地震响应分析。结构地震反应分析表明,结构在附加耗能器状态下,位移、层间位移角、剪力都有所降低。阻尼器明显起到了耗能减震作用。
In order to research energy dissipation and earthquake mitigation effect of Viscous dampers in high-rise building, elastoplastic time history analysis of a high-rise isolated structure based on ETABS finite element analysis program was implemented under imput of intensity 7 earthquake. Earthquake response analysis of structures showed the displacement, inter-story displacement angle, story shear of structure was reduced under the statement of adding viscous dampers. Viscous dampers achieved the function of reducing earthquake response.
