U U-TYPE GIRDER WITH DUAL-PRESTRESSING AND CONSTRUCTION METHOD THEREWITH
Disclosed are a U-shaped girder by dual-prestressing and a bridge construction method using the same, which allow compressed stress by tendon to be introduced into a lower edge of a central shaft as first prestressing and allow the compressed stress accumulated on an upper edge of the central shaft to be offset by tensile stress introduced by reaction by a compression steel material as arch blocks and second prestressing, thereby optimizing a cross section to be effective for a minor plate girder.
1차 프리스트레싱으로서 긴장재에 의한 압축응력이 중립축 하연에 도입되도록 하고, 중립축 상연에 누적되는 압축응력은 아치블록과 2차 프리스트레싱으로서 압축강재에 의하여 반력으로 도입되는 인장응력으로 상쇄시켜 단면 최적화에 의하여 소수주형 거더로 효과적인 듀얼 프리스트레싱에 의한 U형 거더 및 이를 이용한 교량시공방법이 개시된다.
