CONCRETE-COMPOSITE CROSSBEAM AND CONSTRUCTION METHODS USING THE SAME

摘要

PURPOSE: A steel framed concrete composite beam and a construction method using the same are provided to effectively resist bending moment concentrated on the center of the beam by forming a steel frame in the center part of a concrete member. CONSTITUTION: A steel framed concrete composite beam comprises a concrete member(10), a steel frame(12), a tension bar, and stirrup bars(26). The concrete member is formed in a hexahedron shape. The steel frame is installed in the center of the concrete member except both ends. The tension bar is embedded in the concrete member in a longitudinal direction. The stirrup bars are arranged in the concrete member at equal intervals to cover a lower flange of the steel frame.
