本文通过对辽化体育馆工程屋盖结构设计方案的分析,探讨了中,小型体育馆屋盖结构合理方案的选择问题,作者根据这类建筑平面的特点,提出了四支点平面桁架的屋盖方案,它与常用的网架方案相比,其综合用钢量指标及造价均大大降低、并方便了施工和安装,缩短了工期,取得了较大的经济效益,同时,这种方案能使看台与两侧多层框架现浇在一起,从而增强了房屋的整体刚度,提高了这种大跨度结构的抗震能力,本文所建议的方案,对于常用的中小型体育馆工程的屋盖设计,具有普遍的参考价值。
Based on the analysis of the design of roof structure of Liaohua Gymnasium, this paper discusses the selection of rational schemes for the roof structure of small and medium-sized stadiums. Based on the characteristics of this type of building, the author proposes a four-point planar truss roof project. Compared with the commonly used grid solutions, its comprehensive steel consumption indicators and cost are greatly reduced, and the construction and installation are convenient, the construction period is shortened, and greater economic benefits are achieved. At the same time, this kind of solution can make the The multi-layer frames on the two sides are casted together, which enhances the overall rigidity of the house and improves the seismic resistance of this large-span structure. The proposed scheme is universal for the roof design of commonly used small and medium-sized stadiums. Reference value.
