STEEL PIPE GIRDER BRIDGE REINFORCED BY R.C

摘要

PURPOSE: A steel pipe girder bridge reinforced with concrete is provided to improve composite action steel and concrete. CONSTITUTION: A steel pipe girder bridge reinforced with concrete comprises a bridge deck(10), a plurality of steel pipe girders(20), a plurality of cross beams(30) and a lower structure(40). The bridge deck makes pedestrians and vehicles possible to pass through. The steel pipe girder is installed in the lower part of the bridge deck in the longitudinal direction of the bridge deck. The steel pipe girder comprises a circular steel pipe(210), a concrete filler(220) and a shear connector for a girder(230). The concrete filler is filled inside the circular steel pipe. The shear connector for the girder is located between the concrete filler and the circular steel pipe for the composite action. The cross beam is installed between the steel pipe girders in the traverse direction of the bridge deck. The lower structure supports the steel pipe girder.
