［摘要］苏宁易购总部VIP门厅是一个单层钢结构建筑，为了实现建筑设计的大柱网、高细柱，结构设计采用一种新型的结构体系——带柔性支撑的钢框排架结构，通过对其整体力学性能的计算分析和比较研究，以及对关键节点连接做法的构造研究，论证了这一新型结构体系的可行性。为了达到建筑设计要求的双曲屋面，结构设计采用一种斜置压型钢板与正放钢梁的搁置连接方法，解决了双曲屋面中压型钢板组合楼板与承重钢梁的连接问题，实现了压型钢板组合楼板在双曲屋面中的应用。相关内容可为类似工程的结构设计提供参考。

Abstract:Suning Yigou headquarters′ VIP lobby is a single-storey steel structure building, in order to realize the design of large column network and high-thin columns in architectural design, a new structural system, steel frame bent structure with flexible support, was adopted in structural design. The feasibility of this new structural system was demonstrated through the calculation and comparison of its overall mechanical properties and the structural study of the connection method of key joints. In order to meet the requirements of architectural design for hyperbolic roof, a method of shelving connection between oblique profiled steel plate and positive steel beam was adopted in structural design, which solves the connection problem between medium-pressure profiled steel plate composite floor and load-bearing steel beam in hyperbolic roof, and realizes the application of profiled steel plate composite floor in hyperbolic roof. Relevant contents can provide reference for the structural design of similar projects.

Keywords:steel frame; flexible support; hyperbolic roof; composite floor
