Steel composite beam bridge is a kind of bridge structure, in which steel composite beam is the main bearing structure. Steel composite beams are usually welded from three steel plates to form a steel beam with an I-shaped section. This kind of structure has the advantages of high bearing capacity, strong crossing ability, ductility, good impact toughness, good seismic performance and so on. At the same time, the construction period is short, the quality is controllable, it is easy to repair and replace after damage, and the waste steel can be recycled, which meets the requirements of environmental protection and sustainable development.
In the composite steel plate girder bridge, the steel beam and the concrete bridge panel are joined together by connecting pieces to bear the longitudinal bending moment of the bridge. According to the different connector, the composite beam can be divided into rigid composite beam, elastic composite beam and flexible composite beam. In addition, according to the type of load, there are also dead and live load composite beams and continuous composite beams.
