张家港双子楼酒店式公寓塔楼建筑高度为303m,结构采用型钢混凝土框架+钢筋混凝土核心筒+Y向伸臂桁架混合结构体系,为超B级高度的超限高层。主要介绍了工程上部结构设计,包括小震作用下的弹性分析,外框柱承担的剪力调整,风洞试验结果与规范风荷载取值的比较,“有限刚度”加强层设计等,最后对特殊的异形角柱、穿层柱设计进行了较为详细的介绍。 Zhangjiagang Petronas Towers serviced apartment tower building height of 303m, the structure of steel reinforced concrete core frame + Y core boom + Y-shaped truss mixed structural system, as the ultra-B high level over the top. This paper mainly introduces the design of the superstructure of the project, including the analysis of elasticity under the action of minor earthquakes, the adjustment of the shear force borne by the outer frame, the comparison between the wind tunnel test results and the standard wind load value, the design of “limited stiffness” Finally, the special shaped corner column, through the design of layering column carried out a more detailed introduction.
