[摘要]350m高的深圳汉京中心是目前国内已建成的最高无混凝土核心筒全钢结构建筑。该项目建筑平面特殊,存在平面整体性差、抗侧刚度不足、平面重心与竖向刚度中心距离较大等难题,由美方设计的结构方案不是非常理想且用钢量偏大。本地设计团队在初步设计中后期,深入分析了结构体系的特点并进行了一系列成功的调整优化,在整体指标没有明显变化的前提下减少了近30%的用钢量,并大幅提升了建筑品质。

Abstract:The 350m high Shenzhen Hanking Center is the highest concrete-free steel corewall structure building in China. Because of the special plane of the building, there were some problems such as poor plane integrity, insufficient lateral stiffness, and large distance between the plane center of gravity and the vertical stiffness center. In addition, the structural scheme designed by the US was not very ideal and the steel consumption was too large. In the middle and later stage of the preliminary design, the local design team deeply analyzed the characteristics of the structural system and carried out a series of successful adjustments and optimizations. Under the premise that the overall index did not change significantly, the steel consumption was reduced by nearly 30%, and the building quality was greatly improved.
Keywords:Shenzhen Hanking Center; steel structure; structural system; structural optimization
