摘　　要：随着社会经济发展,我国高层建筑数量与日俱增,减震、隔震技术逐渐在高层结构中应用,并且提出了减震、隔震装置联合使用的新型组合减隔震技术。本文为研究高层组合减隔震结构中阻尼器布置位置对隔震效果的影响,针对高烈度区某框架-核心筒结构采取传统抗震、隔震、隔震-隔震层减震和隔震-非隔震层减震4种抗震方案,并选取7条地震波,通过Perform-3D软件对其分别进行罕遇地震和极罕遇地震下的弹塑性时程分析。对比结构宏观指标发现:相比隔震结构,组合减隔震结构能有效降低地震响应;黏滞阻尼器设置在非隔震层的组合减隔震结构抗震效果最佳,提高了结构安全度。With the development of socio-economic development,the number of high-rise buildings is increasing in China.Energy dissipation and seismic isolation technologies have gradually been applied in high-rise structures.In addition,it proposes a new combination of seismic dissipation and isolation devices.This article is to study the effects of the layout of dampers in the high-rise composite seismic dissipation and isolation structure.Four aseismic schemes are selected for a frame-core wall structure in high seismic region:The traditional aseismic,seismic isolation,seismic isolation-isolation layer dissipation and seismic isolation-non-isolation layer dissipation,and 7 earthquake waves are selected to analyze the elastic-plastic time-history of rare and extremely rare seismic through software Perform-3D.Comparison the structure macro indicators found:Compared with the aseismic structure,the combined seismic isolation structure can effectively reduce the seismic response;the composite structure with viscous damper installed in the non-isolated layer has the best aseismic effect and improves the safety of the structure.
