摘要
介绍了南京会展中心主展厅屋架结构的主要设计内容.主展厅屋架最大跨度74m,采用张弦梁结构作为其主承力体系,张弦梁两端通过板式橡胶支座支承于下部单排框架柱顶。与常规张弦梁不同,本工程张弦梁两端带悬挑跨,悬挑跨对单榀梁张拉成形产生不利影响.对屋架结构的结构体系、荷载分析、静力承载力分析、整体稳定性分析、节点设计等内容做了阐述,旨在为类似工程提供参考与探讨.
The design of roof structure for Exhibition Hall in Nanjing Convention and Exhibition Centre is presented.The structure,with the maximum span of 74m,is designed using beam string structure as its main load-bearing system.Beam string structures are supported by plate type elastomeric pad bearings on the top of the lower columns of both single row frameworks.Different to the conventional beam string structure,each beam string structure in this project has cantilevered beams on both of its two ends,which will bring a negative impact on its tension forming.The structural system,load analysis,static calculation and analysis,overall stability analysis and detailing of nodes are introduced in this paper to provide a reference and discussion for similar projects.
