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
