摘要: 安阳文体中心体育馆是承办地区性综合比赛及全国单项比赛的 6 000 座大型乙级体育馆。 建筑主体下部采用钢筋混凝土框架结构,钢结构屋盖采用双向桁架结构,基础形式为桩承台,桩型为后注浆钻孔灌注桩,嵌固端设置在基础顶。 钢屋盖跨度较大,采用梁支撑有效减小梁跨度,并为桁架提供侧向稳定支撑,提高整体受力性能;采用倒三角桁架的加强撑平衡腹杆面外力、保证腹杆稳定。 对整体结构进行计算分析、钢屋盖计算分析、施工仿真与实施分析。 分析结果表明:整体结构受力合理、传力路径清晰、节点构造可靠,施工过程中不同阶段的结构内力、变形同结构设计分析存在较大差异,设计应重视大跨屋盖钢结构的施工仿真。

Abstract: Anyang Cultural and Sports Center Stadium is a 6 000 seats Class B gymnasium designed for regionalcomprehensive competitions and national individual competitions. The gymnasium is a reinforced concrete frame structure,the steel roof adopts bidirectional truss steel structure, the foundation form is pile cap, the pile type is post-grouting boredpile, and the fixed end is set on the top of the foundation. The span of the steel roof is large, beam support is used toeffectively reduce the span of the beam, it also provides lateral stable support for the truss to improve the overall mechanicalperformance. Inverted triangular reinforce support is used to balance the external force on the belly rod surface and ensurethe stability of the belly rod. Overall structural calculation analysis, steel roof calculation analysis, construction simulationand implementation analysis were carried out. The analysis results show that the overall structure has reasonable force,clear force transmission path and reliable joint structure,the internal force and deformation of the structure at different stagesin the construction process are quite different from the structural design and analysis,the design should pay attention to theconstruction simulation of steel structure with large-span roof.
