Project proposal of foot bridge with "Lira" type supports.
Stuctural solutions: Bridge span is 70 meters. Framework - steel arch of rectangular hollow section. Supports - lyre-shaped steel structures of rectangular hollow section. Bearing elements of the surface - beam system, that consists of rolled and welded beams. Modal analysis for combined action of dead and reduced (50 kg/m2) effective loads has been carried out.
Structural analysis has been carried out for combined action of following loading states: - dead loads; - effective loads by sections (28 mutually complementary loads); - wind loads considering mean and pulsation component; - temperature.
