摘　　要：山西体育中心体育馆、游泳跳水馆、自行车馆为一大型复杂的体育建筑。根据建筑平面布置,结合结构设计的具体情况,下部混凝土结构在三馆之间的连接体处设置4条永久缝,划分为5个结构单元;自行车馆与体育馆之间的连接平台与两馆采用滑动连接,体育馆与游泳跳水馆之间的连接平台与两馆之间结构缝采用双柱形式。上部钢结构屋盖连成整体支承于下部5个混凝土结构单元上。基础为预应力混凝土管桩。下部为钢筋混凝土框架剪力墙结构,上部钢结构罩棚采用多重弦支网壳+空腹桁架+鱼腹桁架组合体系。重点介绍上部钢结构的构成,并对整体结构在重力、风、地震、温度等多种荷载作用下的变形受力性能进行了详细分析,进行了施工张拉模拟分析、日照非均匀温度场效应研究、线性和非线性屈曲稳定分析、静力PUSHDOWN分析、多点输入地震反应分析、动力弹塑性分析、关键节点的局部有限元分析、断索分析等。Shanxi Sports Center is a complex long span structure with gymnasium, swimming and diving pavition and bicycle pavilion. Therefore, the whole superstructure can be divided into five districts. Foundation adopts prestressed concrete pipe pile. Reinforced concrete frame-shear wall structure is adopted in the lower structure, and muhiple suspended lattice steel structure and vierendeel truss are adopted in the upper steel structure. The whole steel structure is supported by five districts sub reinforced concrete structure. Several key points of structural design are introduced, including form of upper steel structure, whole structural analysis, load analysis, buckling analysis, PUSHDOWN analysis, cable break progressive analysis, seismic analysis, temperature analysis, tension construction sequences analysis, dynamic elastoplastie analysis and important nodal analysis etc.
