Steel-concrete compositebridge is a new type structure in which the steel and the concrete are integrated by connectors to take advantage of the respective properties of tension and compression.
In order to let the slabs help the top chords of the steel trusses resist the giant compressive forces, slab truss composite structures are used throughout the main bridge.
