摘　　要：结合宁波某医院项目,探讨7度区重点设防类结构的减震设计。该项目采用减震技术,通过在合适的位置布置粘滞阻尼器提高结构的抗震性能,采用YJK和SAP2000等软件对该结构进行小震及大震情况下的受力分析,并对7度区减震结构的经济性进行了对比分析。经计算分析可知:采用该粘滞阻尼器的消能减震结构,在多遇地震下即耗能,提供附加阻尼比,层间位移角明显减小。罕遇地震作用下,减震结构与非减震结构的水平位移比为0.87,减震效果较明显,且本项目采用粘滞阻尼器后含钢量减少,具有良好的经济效益。Combined with a hospital project in Ningbo,this paper discusses the shock absorption design of key fortification structure in 7 degree seismic region.In this project,damping technology is adopted to improve the seismic performance of the structure by placing viscous dampers at appropriate locations.YJK and SAP2000 software are used to analyze the force of the structure under small and large earthquakes,and the economy of the structure in 7 degree region is analyzed by comparison.Through calculation and analysis,it can be seen that the energy dissipation structure with viscous damper can dissipate energy under frequent earthquakes,which provides additional damping ratio and reduces the displacement angle between layers obviously.Under rare earthquakes,the horizontal displacement ratio between the damping structure and the non-damping structure is 0.87,and the damping effect is obvious.Moreover,through analysis shows that the steel content is reduced after adopting the viscous damper,which has good economic benefits.
