| 摘 要： | 钢筋混凝土框架结构采用轻钢结构加层后,整体结构刚度沿高度分布非常不均匀。在结构顶部的钢框架内设置粘滞阻尼器,采用地震时程分析方法并考虑材料的非线性因素,对某加层后的框架结构在多维地震作用下的非线性动力反应进行研究。结果表明,设置粘滞阻尼器来调节地震作用对结构的不利影响,可显著减小加层结构的层间位移,需进行多维地震作用下的时程分析才能真实地反映其地震响应。

| Abstract: | The overall structural stiffness along the height of the distribution is very uneven after the light steel structure layer added to the reinforced concrete frame structure.Viscous dampers are set at the top of the structural steel framework,multi-dimensional nonlinear dynamic response of one frame structure is analyzed with the seismic time-history analysis method,and the material non-linear factors are considered at the same time.The results show that interlayer displacement is reduced after setting viscou... |
