［摘要］沈阳金廊超高层塔楼地下5层，地上71层，建筑檐口高度为330m，采用钢骨混凝土框架-钢筋混凝土核心筒结构。通过比选结构加强层设置方案，确定了加强层数量、伸臂桁架及腰桁架的设置方案。基于有限刚度原则，伸臂桁架腹杆采用防屈曲支撑，以避免加强层刚度突变。针对最小剪重比不满足规范要求的情况，采用放大楼层地震力和调整规范反应谱的方法提高楼层剪重比。塔楼核心筒在49层及以上楼层收进，收进部位及其上下1层按性能化设计理念采取加强措施，以减弱结构突变程度。对结构进行了弹性和弹塑性时程分析，结果表明，结构可满足预设的性能目标。最后介绍了结构体系关键构件的设计方法。

Abstract: The super high-rise tower in Shenyang Golden Corridor has 71 floors overground and 5 floors underground with building cornice height of 330m. The building adopts steel reinforced concrete frame-reinforced concrete core walls structure. Through comparison and selection of structural reinforcement layer setting plans, the number of reinforcement layers, the setting plan of outrigger truss and waist truss were determined. According to the limited stiffness principle, the buckling restrained braces were used in the web of outriggers truss to avoid the stiffness mutation of strengthening layer. In view of the situation that the minimum shear-gravity ratio does not meet the code requirements, the method of amplifying the seismic force of the floor and adjusting the code response spectrum were adopted to increase the floor shear-gravity ratio. The core tube of the tower is retracted on the 49th floor and above, and the retracted part and the upper and lower floors adopt strengthening measures according to the performance-based design concept to reduce the degree of structural mutation. The elastic and elastic-plastic time-history analyses of the structure were executed, the results show that the structure can fulfil expected seismic performance targets. Finally, the design methods of key members were introduced.
