Bridge using Composite Structural Member of Corrugated Steel Web and Concrete Member and Constructing Method of such Bridge

PARK YOUNG HO

Abstract

The present invention relates to a bridge using a composite structural member of a concrete member and a corrugated steel beam and a construction method thereof, in which a shear resistance tube is installed on a flange of a corrugated steel beam and embedded in a concrete member in a composite structural member where the concrete member is integrated with the corrugated steel beam and thereby the structural integration of the corrugated steel beam and the concrete member is reinforced and the bending stiffness and the shear stiffness of the composite structural member are enhanced. In addition, a tendon is arranged using the shear resistance tube to apply tensional force in a longitudinal direction, and therefore the bending stiffness is reinforced effectively in response to a bending moment.

본 발명은 파형강판 빔에 콘크리트 부재가 일체로 결합되어 있는 접합구조체에서 파형강판 빔의 플랜지에 전단저항관(管)이 설치되어 콘크리트 부재에 매립됨으로써 콘크리트 부재와 파형강판 빔 간의 구조적인 일체화가 더욱 강화됨과 동시에 접합구조체의 휨강성과 전단강성이 향상되며, 전단저항관을 이용하여 긴장재를 배치하여 종방향으로 긴장력을 도입할 수 있게 되어 휨모멘트에 대응하여 효과적으로 휨강성을 보강할 수 있는 구성의 “파형강판 빔과 콘크리트 부재의 접합구조체, 이를 이용한 교량 및 그 시공방법”에 관한 것이다.
