Steel Carrying Structures of the Roof over the Lokomotiv Moscow Stadium Stands

摘要

The 30,000-seat Central Arena of the "Lokomotiv" Sports Complex is designed to host soccer matches. Its stands are protected by a translucent roof (canopy) that sits on radial trusses, supported by an inner ring and outer concrete pillars. The spatial system of radial trusses, linked together by ring beams, is covered with translucent roof panels. Four raked ∧-shaped reinforced concrete towers are installed in four corners of the roof. The tower tops keep a system of main sagging cables in place. The pairs of tilted suspension cables are attached to the main cables. The inner ring box girder is fixed to one suspension cable from the pair while the other suspension cable is fixed to the outer pillar of the main frame. The ∧-shaped concrete towers are pulled back by two anchored guy cables attached to the tower tops. Numerical stress-strain analysis of virtual design options has yielded an optimal roof design. The system behavior during erection and operation was analyzed, the strength of applied materials, manufacturability and installation procedures were optimized. Design and construction period: May 2000 - December 2001.
