Abstract: 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.
Keywords: sport center; gymnasium; steel structure; lapping truss; loading value; node analysis; support design
