STEEL COMPOSITE GIRDER AND BEAM WITH A STEEL MATERIAL AND REINFORCED CONCRETE FOR SUPPORTING BENDING MOMENT

摘要

PURPOSE: A steel composite girder and beam with a steel material and reinforced concrete are provided to improve structural efficiency by increasing bending compressive stress and shear stress.;CONSTITUTION: A steel composite girder with a steel material and reinforced concrete is comprised as follows. A steel material and reinforced concrete is integrated in a negative moment section of the steel composite girder. A positive moment section of the steel composite girder is composed of H-shaped steel materials. Stud bolts(8) are welded to the upper and lower flanges(5) and web(6) of the steel material of the negative moment section. C-shaped stirrup bars(9) are welded to the bottom surface of the upper flange and the top surface of the lower flange to be separated from each other.;COPYRIGHT KIPO 2013
