【摘要】 采用一个带加强层框架-核心筒结构的实际工程模型,分别建立其带加强层的框架-核心筒模型和带黏滞阻尼器的框架-核心筒模型。运用ETABS软件对二者进行模态分析、反应谱分析和弹性时程分析,对比多遇地震下的抗震性能。研究结果表明:加强层结构是通过加强层来增加结构的整体刚度,增大了结构地震反应,黏滞耗能减震层结构是通过黏滞阻尼器的滞回效应来耗散输入结构的地震能量,减小结构地震反应;耗能减震层结构比加强层结构能更有效地控制结构的位移、内力及应力的地震反应;加强层增加结构整体刚度,同时也引起结构内力与位移的突变;耗能减震层结构在减震层处的位移、内力及应力的突变均小于加强层结构。更多还原

【Abstract】 A practical engineering model with strengthened story frame-tube structure is used to establish respectively the frame-tube model with Strengthened story and the frame-tube model with viscous dampers. The modal analysis,response spectrum analysis and elastic time history analysis are carried out by using ETABS software to compare the seismic behavior of the two models. The results show that: the Strengthened story structure is formed by Strengthened story to increase the overall stiffness of the structure,increasing the seismic response of structure,energy viscous damping story structure is formed by the viscous damper hysteresis effect to dissipate the seismic input energy,reduce the structural seismic response. The seismic response of damping story structure than strengthened story structure can more effectively control the displacement and internal force of structure stress. Strengthened story increases the overall stiffness of the structure,but also cause structural internal force and displacement of mutation. The displacement,internal force and stress of the structure of the energy dissipation layer in the damping layer are less than that of the Strengthened story structure.更多还原
