Abstract and Keywords

Abstract: In this paper, a seven-story frame structure is taken as an example. Two kinds of energy dissipation components, viscous damper (VD) and metal damper, are selected to carry out time history analysis under frequent and rare earthquake conditions. The ETABS structural analysis software is used to calculate and compare the seismic responses such as interlayer displacement angle, interlayer shear force, energy dissipation and maximum acceleration of the original structure, structure with VD and structure with mixed arrangement of metal damper and VD under different working conditions. The actual damping effect of mixed arrangement of metal damper and VD and the hysteresis and energy dissipation of the damper under two kinds of seismic conditions are highlighted. The analysis results show that the structure with mixed arrangement of metal damper and VD can better control the seismic response of the frame structure, especially under large earthquakes.

Keywords: viscous damper(VD); metal damper; seismic response; hysteretic curve; time history analysis

摘要和关键词

摘要: 文章以某栋7层框架结构为例, 选用黏滞阻尼器(viscous damper, VD)和金属阻尼器2种消能构件, 分别进行多遇和罕遇地震工况下的时程分析, 通过ETABS结构分析软件计算并分析对比原结构、增设VD、金属阻尼器和VD混合布置在不同工况下的层间位移角、层间剪力、能量耗散、最大加速度等地震响应, 对比突出金属阻尼器和VD混合布置的实际减震效果以及2种地震工况下阻尼器的滞回和耗能情况。结果表明, 金属阻尼器和VD混合布置的结构能更好地控制框架结构的地震反应, 特别是在大震下控制地震响应效果突出。
