大庆市奥体中心体育馆屋盖结构选型及设计

大庆市奥体中心体育馆屋盖结构采用主要由立体拱桁架组成的多层次传力的复杂空间受力体系,并引入幕墙桁架参与主结构受力,体现了结构技术与建筑艺术完美结合的特点。依据建筑造型要求和下部支承条件,对所提出的3种屋盖结构方案进行概念设计选型,并对优选出的方案进行计算分析,通过对比各种设计指标最终得到最优的结构方案;最后根据选型得到的结构方案进行结构设计。结果表明:该结构方案不仅能够完全满足建筑造型及使用功能要求,而且受力合理、经济性较好。

STRUCTURAL SELECTION AND DESIGN OF GYMNASIUM ROOF IN DAQING OLYMPIC SPORTS CENTER

Daqing Olympic Sports Center gymnasium's roof uses a complicated multi-level force transmission spatial structure,which is mainly composed by stereo trussed arch. And the truss of the curtain wall is brought in the main structure to bear stress. The gymnasium's roof is a perfect combination of structure technology and architectural art. This paper introduced the structural selection and design of the roof in detail. First,according to the supporting conditions and the architectural modeling,three roof structure schemes were given. Then concept design was brought on and the unreasonable structure scheme was removed. Based on which,the rest schemes were computationally analyzed,and kinds of design index were compared. Moreover,the best structure scheme was gotten. In the end,the roof structure is designed,and the result shows that the structure scheme not only can meet the requirement of architectural shape completely,but also has good mechanical performance and economy.
