不规则椭圆形弦支穹顶钢屋盖结构设计与分析
Structural Design and Analysis of an Irregular Elliptical Suspen-Dome Steel Roof
赤壁市体育中心体育馆钢屋盖为大跨度空间结构,平面投影呈椭圆形,整体跨度为137.8 m×97.6 m,由内外两圈钢骨混凝土柱支撑。根据柱的位置将屋盖划分为内场与外场两大区域:内场钢屋盖采用不规则椭圆形弦支穹顶结构,其平面投影跨度为80.7 m×67.2 m;外场钢屋盖主体为单层网壳结构,局部大跨度区域采用张弦梁结构,最大跨度达33.8 m。为保障结构设计合理,本文采用Midas Gen软件对钢屋盖开展杆件应力分析、模态分析、温度作用分析、屈曲分析、变形分析及施工模拟分析。计算结果表明,该钢屋盖各项指标均满足现行规范要求。文中还详细介绍了预应力索的选型与受力分析、计算模型优化过程及关键节点构造做法,相关设计思路与技术措施可为同类工程提供参考。
The steel roof of the Chibi Sports Center Gymnasium is a large-span spatial structure. Its planar projection is elliptical, with a span of 137.8 m × 97.6 m, and it is supported by inner and outer rings of steel-reinforced concrete columns. According to the column positions, the steel roof is divided into inner and outer fields. The steel roof of the inner field adopts a suspen-dome structure with an irregular elliptical plan projection and a span of 80.7 m × 67.2 m. The steel roof of the outer field adopts a single-layer latticed shell structure, and a beam-string structure is used in the local large-span region, with a maximum span of 33.8 m. To ensure the rationality of the structural design of the steel roof, the Midas Gen software was used to conduct member stress analysis, modal analysis, temperature effect analysis, buckling analysis, deformation analysis and construction simulation analysis on the steel roof. The calculation results show that all structural indicators of the steel roof meet code requirements. This paper also elaborately introduces the selection and analysis of prestressed cables, the adjustment process of calculation model, and the key joint configurations. The design methods and measures adopted in this project can serve as a reference for similar engineering projects.
