Description
The foot bridge, crossing the river Otava above the weir near the Wenceslas suburb, was designed with regard to an architect´s desired shape, layout and spatial intents. Two spans of the bridge, cable stayed and asymmetric suspension one, meet on the pillar situated in the river forming the ground plan angle 1350. Both spans consist of triangular steel lattice truss made from tubes and orthotropic steel deck of width 3,3 m. Asymmetric suspension span of length 81,7 m is suspended on two ropes ø 76mm using solid bar hangers with thread M20 spacing of 6 m. The thin pylons are 16 m high only, and inclined 19° to the side and 6° backwards (away from the river). Position of the top of pylons, pinned to the top chords of the truss, is defined by the main ropes, top horizontal tension tube and two backward tendons with thread M90 anchored also to the upper chord tubes of the truss. Cable stayed span of length 46,7 m is suspended on three twins of tendons with thread M36. The pylons are 9,7 m high only. Position of the top of pylons, pinned to the top chords of the truss, is defined by six front stays, top horizontal compressed tube and two backward stays with thread M76 anchored to one common point to the abutment.
