摘要
介绍了肇庆新区体育中心专业足球场和体育馆的钢结构设计。其中,专业足球场为悬挑钢箱梁结构,体育馆为双连体弦支穹顶结构。通过结构选型、特征值分析、反应谱分析、稳定性分析以及弹性分析等方面阐述肇庆新区体育中心结构特点。针对计算过程中出现结构薄弱点,采取控制钢结构应力比、加强节点构造措施以提高其安全储备。屋盖钢结构设计均能满足规范要求,并能有效实现建筑形态。
The steel structure designs of professional football stadium and the gymnasium in the Zhaoqing New District Sports Center were introduced. Among this,the professional football stadium is the cantilever steel box girder structure,and the gymnasium is the double connected suspendome structure. The structural characteristics of Zhaoqing New District Sports Center were illustrated based on the structural system selection,eigenvalue analysis,response spectrum analysis,stability analysis and elastic analysis. In view of the structural weaknesses that appeared in the process of calculation,measures of taking control of the steel structure stress ratio and strengthening the node construction measures were taken to improve its safety reserve. Roof steel structure design can meet the specification requirements,and can effectively achieve architectural forms.
