摘　　要：北京南站高架层需要对称安装两组双面LED显示屏,每面屏体质量均为5.79t,要求显示屏位于结构柱的两侧并带有一定的倾斜角度。为保证结构安全,同时兼顾美观和实用性,对多种显示屏支撑结构方案进行计算分析和优选,采用空间钢桁架作为支撑结构,并进行详细的计算、分析和连接节点的设计。另外,对支撑结构的施工进行简要介绍,可为同类工程借鉴。Two sets of double-face LED display screens will be installed symmetrically at overhead floor of Beijing South Railway Station and the weight of per display face is 5.79 t. The display screens should be installed at each side of the steel columns with inclination angle. To guarantee the safety, function and beauty of the display screens, calculation and optimization ＇of many supporting structure projects are conducted and spatial steel truss is adopted. Calculation and analysis are conducted by finite element method and the design of connection joints is provided. The construction process of the spatial steel trusses is introduced briefly. The design and construction may be a reference for similar projects.
