摘　　要：大跨度体育场馆造型结构形式复杂多样,由于跨度大,结构的几何非线性程度高,结构设计由稳定性控制。以某复杂大跨度体育场馆为分析对象,对该结构的大跨度单层空间网格结构进行选型,分别建立了凯威特型、施威德勒型、联方型3种不同空间网格形式下的大跨度体育场馆模型,利用3D3S14.0软件对不同网格形式下的体育场馆进行整体稳定性分析。在控制用钢量及控制K值不变条件下,分别对比不同形式空间网格结构的整体稳定性。研究表明,联方型空间网格的K值为17.5,整体稳定性最好。The long-span stadium modeling structure system is complex and diverse.Due to the long-span and high degree of geometric non-linearity of the structure,the structural design is often controlled by stability.A complex long-span stadium is taked as the object of analysis,the long-span single-layer spatial grid structure is selected,and three different spatial networks of Kiewitt type,Schwedler type,and joint square type are established.The long-span stadium model in the grid forms uses 3D3S14.0 software to analyze the overall stability of the stadium under different grid forms,and the different forms of spatial grid structure under the conditions of controlling the amount of steel and controlling the K value.For overall stability,conrolling the K value of the joint square space grid is 17.5,which is the optimal overall stability.
