Zusammenfassung:	Disclosed is a steel-concrete composite bridge construction method using prestress introduction during erection of a bridge. According to the present invention, the steel-concrete composite bridge construction method may comprise: a step of mounting a steel girder on a foundation; a step of introducing prestress with respect to the mounted steel girder; a step of depositing at least a portion of concrete to form a concrete slab on the steel girder into which the prestress is introduced; and a step of removing the prestress introduced to the steel girder as the deposited concrete is cured for a composite cross section to be formed. As such, construction costs are able to significantly be reduced. 가설중 프리스트레스를 도입한 강합성 교량 시공 방법이 개시되며, 본원의 강합성 교량 시공 방법은 강거더를 기초 상에 거치하는 단계, 거치된 상기 강거더에 대하여 프리스트레스를 도입하는 단계, 프리스트레스가 도입된 상기 강거더 상에 콘크리트 슬래브 형성을 위한 콘크리트를 적어도 일부 타설하는 단계, 및 타설된 상기 콘크리트가 양생되어 합성단면이 형성되면 상기 강거더에 도입된 프리스트레스를 제거하는 단계를 포함할 수 있다.
