摘　　要：随着工业发展,工业建筑朝着大跨度、大柱距、大吨位、超高等方向发展,而国内标准尚未对高大重型钢结构厂房结构体系开展系统研究,其结构体系尚未形成完整结论。以某重型钢结构厂房的设计为基础,对钢管混凝土格构柱-空间管桁架屋盖结构体系应用开展了研究,详细阐述了基础到上部结构的选型思路,通过优化空间结构形式减少围护结构跨度。采用空间有限元软件SAP 2000进行整体分析,并对关键构件、节点计算进行了研究,通过查阅相关资料确定了结构整体稳定、强度、变形、沉降等指标,从整体结构到局部构件进行控制,保证了分析结果的准确性和可靠性。本项目还根据复杂地质条件情况,及时调整管桩的控制标准并应用于后续相关工程,取得了良好的应用效果和经济效益。With the development of industry, industrial buildings are developing towards the direction of large span, large column spacing, large tonnage and ultra high-rise. However, the structural system of tall and heavy steel structure plants has not been systematically studied in domestic specifications, and its structural system has not yet formed a complete conclusion. Based on the design of a heavy-duty steel structure plant, the application of the roofing system composed of concrete-filled steel tubular lattice column and spatial pipe truss was studied. The selection idea from foundation to superstructure was described in detail, and the span of the enclosure structure was reduced by optimizing the form of spatial structure. The finite element software SAP 2000 was used for the overall analysis, and the calculation of key components and joints was studied. By consulting relevant information, the overall stability, strength, deformation, settlement and other indicators of the structure were determined, which were controlled from the overall structure to local components to ensure the accuracy and reliability of the analysis results. According to the complex geological conditions, the control standards of pipe piles were adjusted in time and applied to subsequent related projects, which had achieved good application effect and economic benefits.
