Trussed Bridges
Abstract: Trussed railway bridges offer a unique structural advantage by efficiently distributing the load between the truss members and the girder. In such designs, a significant portion of the load is carried by the truss members, which reduces the stress on the bridge girder itself. As a result, the girder in a trussed bridge can be constructed with a reduced thickness compared to bridges that lack a truss system. This optimization …
