摘　　要：钢结构跃层加层在技术、经济等多方面具有明显的优点,但传统的抗震设计方法使其在地震时存在安全隐患。为了解决这一问题,将黏滞阻尼支撑布置于整体式钢框架跃层加层结构中,对常规和消能整体式钢框架跃层加层结构进行地震反应分析,研究黏滞阻尼支撑对结构的减震效果,并给出相关结论。The technique of adding extra-steel structure spanning existing building has many advantages for technology and economy,but traditional seismic design makes it have hidden danger in security when an earthquake happens.For solving this problem,viscous damper bracer is arranged in integral added spanning steel frame structure,and seismic response analysis is done for conventional and energy vanishing integral added spanning steel frame structure,research its effect of damping shake for the structure is researched,and some conclusion about it is also given.

关 键 词：跃层加层钢结构 地震反应分析 黏滞阻尼支撑 减震作用
