BOWSTRING GIRDER BRIDGE

img

Bowstring bridge is an arch bridge in which the outward-directed horizontal forces of the arch are borne as tension by a chord tying the arch ends, rather than by the ground or the bridge foundations. This strengthened chord may be the deck structure itself or consist of separate, deck-independent tie-rods.

  • Much like a through-truss bridge, except that the truss can be a higher, deeper segmental curve.
  • Suitable for 50m - 150m spans.
  • Attractive.
  • Can be constructed on less robust foundations e.g. atop elevated piers/areas of uneven soil.
  • Can be pre-fabricated offsite and hauled or lifted into place.
