摘　　要：介绍了螺栓球节点与焊接球节点相结合的钢网架(壳)结构熟料库屋盖设计的思路,采用MST和3D3S软件进行网架结构设计计算,并建立全钢结构整体模型,经复核验算,焊接球节点强度符合规范要求。使用焊接球与螺栓球节点相结合的网架体系,支座环向杆件无需使用大直径螺栓,降低了施工难度,节省了建造材料和建造成本。This paper introduces the design idea of steel grid(shell)structure clinker silo roof combining bolt sphere joints and welded sphere joints,uses MST and 3D3S software to design and calculate the grid structure,and establishes an overall steel structure model.After reverification,the strength of welded sphere joints meets the requirements of the specification.The grid structure system combining welded sphere and bolt sphere joints is used,and the support circumferential members do not need to use large diameter bolts,which reduces the construction difficulty and saves the construction materials and construction costs.
