摘　　要：鄂尔多斯游泳馆平面呈圆形,跨度130m,屋盖采用大跨钢管桁架结构,沿径向均匀设置36榀平面钢管桁架,桁架汇交于中心加强环。对结构设计难点问题进行探讨,包括大跨度桁架结构的整体布置,中心加强环的具体做法,桁架支座节点的具体做法,为相关工程提供参考。Plane shape of Erdos natatorium is circle and its span is 130 m. The roof is long-span steel zrass structure with 36 plane steel trusses placed uniformly along radius. All trusses intersect at central stabilized ring. In this paper, many key design problems such as the whole structural arrangement of long-span steel truss structure, the detailed design and manufacture of the central stabilized ring and the support joints are discussed. Which can provide some valuable references for the designers.
