摘　　要：天津海河教育园区体育中心体育馆及公共实训中心的屋盖采用空间异形钢网架结构。考虑下部结构分缝情况,将钢结构屋盖分为8个部分,网架1与网架2通过搭接桁架连接在一起,最大跨度约为80m,最大悬挑约为27m;网架3的跨度约为27m,网架4的跨度约为25.2m。对钢结构屋盖的荷载取值、结构布置、设计参数选取、节点分析与设计、支座设计进行了总结和讨论,可为类似工程提供参考。Gymnasium and public training center of Tianjin Haihe Education Park Sport Center adopts the roof structure of special shaped spatial steel grid. Based on the partition of substructure, the whole steel roof is divided into 8 parts. Grid 1 and grid 2 are connected together with a lapping truss and the largest span reaches about 80m while the maximum cantilevered length reaches 27m. Grid 3 span reaches about 27m, while grid 4 span reaches about 25.2m. The loading values, structure arrangement, design parameters, node analysis and design, support design of the steel structure roof were summarized and discussed, which can provide reference for similar project.
