pont à longerons

OBS: Longeron : Pièce secondaire d'un tablier de pont. (Les longerons peuvent s'appuyer sur des pièces de pont ou sur des entretoises.)

OBS: Stringer or stringer beam: A long horizontal member which ties together the heads of trestles in wooden trestle bridges or provides support under a rail, parallel to it, in a steel railway bridge.
