Structural design of a super high-rise multiple-use building

在超高层建筑结构布置时,利用建筑平面中的楼梯间、电梯间较均匀地布置了多个钢筋混凝土筒体,形成多筒体-框架结构,能够为整体结构提供较大的抗侧、抗扭刚度;沿倾斜立面直接布置斜柱,避免竖向构件的转换;超高层平面梁系布置要考虑竖向构件的轴向变形差异;空腹桁架的应用能够有效地减少构件的截面尺寸;超高层建筑结构分析必须采用不同的计算程序进行分析比较。本文结合实际工程的情况,简要介绍了设计、计算方法和结果,供同行参考。

During the structural design of a super high-rise building, several RC tubes were placed at stair room and elevator rooms equably. It formed multi-tube frame structure. It can provide great stiffness of resist lateral drift and torsion. And inclined columns were placed along the slope; it avoided the transfer of vertical components. The difference of axial deformation of vertical compo- nents was taken into account during place the plan beam system. The application of vierendeel truss can reduce the section sizes of members effectively. Super high-rise building must be calculated by different computer programs. In this paper, the design, calcu- late method and results were introduced briefly with a real engineering. It can be a reference for engineers.
