Interior structure of a covered lattice bridge

A lattice bridge is a form of In medicine, a truss is a kind of surgical appliance, particularly one used for hernia patients. See truss (medicine) Truss bridge for a single track railway, converted to pedestrian use and pipeline support. Outer vertical members are in tension, lower horizontal members in tension , shear, and bending, diagonal and top... truss bridge that uses a large number of small and closely spaced diagonal elements that form a lattice.

Originally a design to allow a substantial bridge to be made from planks, rather than heavy timbers, this type of bridge has also been constructed using a large number of relatively light steel members. The individual elements are more easily handled during construction, but the bridge also requires substantial support during construction. A simple lattice truss will transform the applied loads into a thrust, as the bridge will attempt to change length under load. This may be resisted by compression or tension elements within the bridge or may be resisted by the foundations at the end of the bridge.
