Behaviour of load-carrying members of velodromes’ long-span steel roof

Abstract

Long-span roofs have been of an increased interest within the last sixty years. An arch-type steel roof of velodrome with the maximum span, height, and length equal to 109.50, 23.07, and 126.00 m respectively, is considered as the object of the current investigation. The choice of the preferable structural solution and behaviour analysis of load-carrying members of the long-span arch-type steel roof of the velodrome is considered as the aim of the current study. The distribution of internal forces and stresses in the trihedral lattice steel arch with a triangular web such as displacements under the action of design loads were investigated for fixed, double-hinged, and three-hinged static schemes. It was stated that the preferable structural scheme is the fixed arch.
