Analysis of Viscous Damper in High-Rise Steel Structure on Anti-Seismic and Wind Resistance Performance

As the application of viscous dampers in high-rise steel structure,it is necessary to introduce the performance of anti-seismic and wind resistance.By finite element analysis software,3D modal of high-rise steel structure was established.Coefficient parameters of viscous damper were analyzed,the rational parameters were proposed,and the elasticity-plastic anti-seismic time-history analysis and random wind vibration were performed.Dynamic characteristics of the structure before and after adding viscous damper were contrasted through anti-seismic and wind resistance.The results show that the responses of earthquake and random wind vibration are reduced by 10% after adding viscous dampers,and responses of random wind vibration are reduced by 50% after adding viscous dampers.
