摘　　要：通过对某7层钢结构及其增设粘滞阻尼器结构进行数值分析,可得在竖向罕遇地震作用下粘滞阻尼器对钢结构有着显著的消能减震作用.较原钢结构,增设粘滞阻尼器钢结构的楼层位移有着11.3%的降幅,楼层层间位移降幅最大达16.4%,说明对于钢结构在实际工程设计中,其抗震性能的提高可以通过增设粘滞阻尼器来实现.Through the numerical analysis of a 7-story steel structure and its structure with viscous damper, the viscous damper has significant energy dissipation and shock absorption effect on the steel structure under the rare vertical earthquake. Compared with the original steel structure, the floor displacement of the viscous damper steel structure has a decrease of 11.3%, and the displacement between the floors is up to 16.4%. It shows that the improvement of seismic performance of the steel structure can be achieved by adding the viscous damper in the actual engineering design.
