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.
