Summary:The present invention relates to a steel girder with a semicircular column bearing stiffener filled with concrete, which can increase resistance to torsion of the steel girder, stably connect an end portion cross beam to the steel girder regardless of a square, and increase structural performance of the bearing stiffener. According to an embodiment of the present invention, the steel girder with a semicircular column bearing stiffener filled with concrete comprises: a steel plate semicircular column welded to be closed in an upper flange, a web plate, and a lower flange of the steel girder in an end portion or a support portion and a position in which a concentrated load works of the steel girder; a tension support installed on an inner surface of the steel plate semicircular column on an extension line of an axial line of a bracket installed parallel to the cross beam that connects adjacent steel girders to each other; and stiffening concrete applied into and integrated with the steel plate semicircular column. 본 발명은 강거더의 뒤틀림 저항성능을 향상시키고, 사각에 상관없이 단부가로보를 강거더에 견고하게 연결할 수 있으며, 지압보강재의 구조성능을 향상시킬 수 있는 콘크리트가 충진된 반원기둥 지압보강재가 형성된 강거더를 제공한다. 본 발명의 적절한 실시 형태에 따른 콘크리트가 충진된 반원기둥 지압보강재가 형성된 강거더는, 강거더의 단부 또는 지점부 및 집중하중이 작용하는 위치에서 강거더의 상부 플랜지와 복부판 및 하부 플랜지에 폐합되도록 용접되어 설치된 강판 반원기둥과; 인접한 강거더를 상호 연결하는 가로보와 평행하게 설치된 브라켓의 축선 연장선상에서 강판 반원기둥의 내면에 설치된 인장지지대와; 강판 반원기둥 내에 타설되어 일체화되는 보강 콘크리트;를 포함한 것을 특징으로 한다.
