V-SHAPED COMPOSITE BEAM HAVING THE MOST COST-EFFECTIVE CROSS SECTION CAPABLE OF EFFICIENTLY UTILIZING CHARACTERISTICS OF A MATERIAL, AND A CONSTRUCTION METHOD OF THE SAME

摘要

PURPOSE: A V-shaped composite beam and a construction method of the same are provided to reduce the amount of used steel material compared to a squared cross-section or a U-shaped cross-section and to reduce the amount of concrete filled in the beam, thereby bringing a cost-effective result as the whole weight of the beam decreases.;CONSTITUTION: A V-shaped composite beam is manufactured by filling concrete(120) in a V-shaped steel beam(110) which is extended in a longitudinal direction. The V-shaped steel beam comprises two side wall portions(111), a lower flange(112), and an upper flange(113); and the two side wall portions, the lower flange, and the upper flange are made of steel or steel sheet. The lower flange horizontally bends lower ends of the two side wall portions to form a horizontal plate shape. The upper flange horizontally bends upper ends of the two side wall portions to form a horizontal plate shape.;COPYRIGHT KIPO 2013;[Reference numerals] (A1,A2) Bending; (B1,B2) Coupling end; (CC) Lengthwise direction(Longitudinal direction)
