Abstract: 본 고안은 피에스에스씨(PSSC: Prestresed Steel and Concrete) 합성거더에 관한 것으로, 하나 이상의 형강(100)이 결합되어 이루어진 형강 구조체(102)에 캠버링을 위한 긴장수단(200)이 결합되고, 상기 형강 구조체(102)의 내측 공간부에 콘크리트(300)가 타설되며, 상기 긴장수단(200)이 상기 형강 구조체(102)의 플랜지 내측영역에 배치되면서 상기 형강 구조체(102)의 중심부를 기준으로 원거리에 위치하도록 하부 플랜지(113)의 직상부에 근접하게 배치되어 구성된다. 이러한 본 고안은 PSC 거더와 강철재 거더의 장점을 모두 갖는 것으로, 교량에 적용하여 거더의 캠버를 시공 전, 후에 조절할 수 있으므로 슬래브의 처짐량을 간편 용이하게 감소시킬 수 있고, 휨 변형에 의한 균열이 발생하지 않는 이점이 있다. 또, 형강 구조체의 내측 공간부에 철근이 배근되고 콘크리트가 타설되어 형강과 콘크리트가 일체화되어 있으므로 강성 및 내하력이 증대되고, 재긴장이 가능하여 유지관리가 매우 용이하게 되며, 경간을 대폭 증대시킬 수 있는 이점이 있다. 또한, 형강에 콘크리트를 타설하여 단면2차모멘트가 증가하므로 구조물의 진동폭이 대폭 감소되는 이점이 있다. 그리고 특히, 긴장재가 형강 구조체의 중심부로부터 원거리에 위치하도록 결합되어 작은 긴장력으로도 요구되는 상향 모멘트를 얻을 수 있으므로 시공할 때에 긴장작업의 비용과 시간을 감소시킬 수 있는 이점이 있다.
