摘　　要：本文运用有限元分析软件ANSYS对采用消能减震新技术的潮汕星河大厦进行了模态分析、瞬态动力有限元分析。该工程的消能部件采用复合型铅粘弹性阻尼器。在确定了复合型铅粘弹性阻尼器试验性能及耗能器布置位置和数量的基础上,计算分析了结构在安装阻尼器前后的模态变化以及遭遇设防烈度对应的罕遇烈度的地震反应。结果表明,在高层建筑中,针对结构的具体特点利用粘弹性阻尼器来改善结构的抗震性能是合理的,消能减震效果是良好的。Chaoshan-xinghe building which was designed with the new anti seismic method of Energy Dissipation was analyzed on modal and Transient Dynamic finite element by the ANSYS software.Mixed mode damper of plumbum-viscoelasticity designed by professor Zhou Yun was adopted as the energy dissipation element.With the behavior、location and number of the dampers confirmed,the structure with and without dampers were analyzed about the modal and responses under rarely occurred seismic intensity according to fortification intensity.
