摘要
以东南大学九龙湖体育馆的异形钢柱支撑的轮辐式张弦梁结构为背景,对结构进行了稳定性、施工方案优化、施工检测等若干关键技术的分析和研究。对轮辐式张弦梁结构的形态、性能、计算模型及分析理论进行了分析和总结,得到了实用的异形钢柱支撑的轮辐式张弦梁结构的施工仿真模拟的方法,并提出提高结构稳定性的建议。通过有限元软件分析选定了九龙湖体育馆异形钢柱支撑的轮辐式张弦梁结构安全合理的施工方案,同时,对张拉过程进行了施工仿真分析,比选并确定张拉方案。进行项目现场实地检测,将检测结果与理论分析结果进行对照分析,证明理论分析结果的正确性和理论分析方法的可靠性。
This paper is concerned with the Jiulonghu Stadium of Southeast University, whose structure form is radiant beam string structure supported by special-shaped steel columns. The stability of structure, construction scheme optimization and construction monitoring are analyzed and researched. The morphology and property of radiant beam string structure is summarized, and the overview of calculation model and analysis theory is provided. The construction simulation analysis method of radiant beam string structure supported by special-shaped steel columns is accessed and recommendations for improving the stability of structure are made. The tension process simulation analysis of radiant beam string structure supported by special-shaped steel columns is carried out. Several possible methods of tensioning are discussed. On account of project site monitoring, comparative analysis is developed on the actual measurement result and the theoretical analysis result, and it proved the correctness of theoretical analysis.
