摘　　要：某工程为屋顶带有53m高塔的L形平面高层结构,文中对结构进行抗震性能设计和计算分析,同时对结构的安全性进行评估,并对屋顶带高塔与屋顶不带高塔、仅将高塔恒载工况和满布活载工况产生的作用力施加于屋面上进行比较,分析了高塔楼的地震反应及对主体结构产生的影响。采取一系列抗震加强措施,使结构能满足规定的抗震性能目标要求。This project is an L-shaped high-rise structure with 53m high tower.Through the seismic performance design of the structure and calculation analysis and assess the safety of the structure.Comparative analysis on the roof with a high-tower with the tower gravity is applied to the roof.Analysis of the seismic response and the impact on the main structure of the high tower,take a series of seismic strengthen measures to enable the structure to meet the seismic performance objectives.
