Abstract:The roof of Dongshan Middle School stadium in Meizhou city is composed of multiple spatial reversed cantilever steel trusses. Adjacent trusses are connected with short steel tubes to form a stable structural system of the whole roof structure to resist the vertical and horizontal loadings. The roof has beautiful architectural modeling and novel structural form. The structural design and force analysis of the steel roof were introduced as well as continuous improvements made in the steel roof structure in the design process. It shows  that through analysis the steel structure satisfies the requirement of stiffness, strength and stability.

Keywords:stadium; space torsional cantilever steel truss structure; steel structure design
