Arch Bridge
Arch Bridge
(OP)
Hi,
Currently I am task to come up with an option/feasibility study on proposing a 250m length and 30m wide single span bridge across a canal. Due to the vertical clearance constrains, I am trying to propose a Tie-Arch Bridge for this project.
Is Arch Bridge the most economical in this situation?
Is the depth of deck structure determined by the spacing of the hangers? I have only space for roughly 2m thick of deck structure, is that adequate?
Thanks.

RE: Arch Bridge
The deck structure (floorbeams, stringers, deck and not including the barrier height) will be close at 6 feet for a deck width of about 90 feet (30 m). The floorbeam alone should be about 7-8 feet (2.5 m) and the stringers will likely be 30 to 36 inches (0.75 to 1 m). The concrete deck would be a noiminal 200 mm or 8 inches.
