哈尔滨国际会议展览体育中心主馆屋盖钢结构设计

哈尔滨国际会议展览体育中心是国内在建和已建成的展览类建筑中规模较大的一个。主要介绍了其组成及结构形式,主馆大跨钢结构的设计过程。重点阐述了主馆大跨张弦桁架体系的结构特点和设计中参数的选择;应用ANSYS软件及自主开发的辅助接口程序,对主体钢结构进行了细致的受力分析。在优化设计的基础上,对施工过程进行了全过程数值模拟,有效地指导了施工中的预应力张拉的实时监测和施工调整控制。分析了张弦桁架的施工稳定性,同时总结了该类结构体系的一些设计特点。

Design of String Structure in Harbin International Conference Exhibition and Sports Center

Harbin international conference exhibition and sports center is a comprehensive public service.It is a larger one among the domestic exhibition architectures which are under construction and constructed.The composition,the structural form and the design process of the large-span steel structure of the main exhibition center are introduced.The selection of design parameters of the large-span truss cable structural system of the main exhibition center is presented.By utilizing the software ANSYS and the self-developed assistant interface programs,load-bearing analysis of the main steel structure is carried out.On base of the optimizing design,the whole-course numerical simulations in construction are carried out,which effectively guides the synchronized monitoring of pretension and adjusting control in construction.The stability of truss cable structure in construction is analyzed and several design characteristics of this kind of structural system are concluded.
