Abstract:The steel pipe trusses covered by PTFE membranes with cable-stayed towers are adopted in order to meet the demand for the architectural style. The total length of the steel roof is up to 360m and the length of the reinforced concrete structure in the second floor is up to 189m due to the limit of the architectural function which demands that seams mustn′t be set, which means that it is a over long structure. The rung-shape cable truss structure is used for the center and the tension of the steels is achieved by the displacement control method.The key technology of the structure is given.
Keywords:steel pipe truss; cable-stayed; membrane structure; rung-shape cable truss
