摘要
文章以某栋7层框架结构为例,通过选用杆式阻尼器和黏滞阻尼墙(viscous damping wall,VDW)2种消能构件,总结阻尼墙的布置及设计模拟方法,通过SAP2000结构分析软件计算,分析对比2种构件在不同工况下的层间位移、层间剪力、能量耗散、最大加速度等地震响应,比较2种减震构件的实际减震效果。分析结果表明,VDW能更好地控制框架结构的地震反应,特别是在大震下控制薄弱层变形方面效果突出。
In this paper,a seven-layer frame structure is taken as an example,and two kinds of energy dissipation members,rod damper and viscous damping wall(VDW),are used to summarize the arrangement and design simulation method of damping walls.Through the calculation of SAP2000 software,the seismic responses of the two kinds of members under different working conditions,such as inter-layer displacement,inter-layer shear force,capacity dissipation and maximum acceleration,are analyzed and compared,and the actual damping effects of the two kinds of damping members are summarized.The results show that VDW has better performance in controlling the seismic response of frame structure,especially in controlling the deformation of the weak layer under the large earthquake.
