DUAL-PRESTRESSING COMPOSITE BEAM AND THE CONSTRUCTION METHOD THEREWITH
The present invention relates to a dual-prestressing composite beam which can optimize a section thereof using an upper steel material by imposing the dead weight of a lower casing block formed in a lower flange of a steel beam on a steel beam when being used as a long span girder. The dual-prestressing composite beam comprises: the lower casing block which is integrally formed with a lower bent flange; and an upper compression steel material which is installed on the upper surface of the steel beam.
강재 빔의 하부플랜지에 형성되는 하부케이싱블록의 자중을 강재빔이 부담하도록 하면서 장경간용 거더로 이용함에 있어서 상부강재를 이용하여 단면을 최적화 할 수 있는 듀얼-프리스트레싱 강합성 빔 및 그 시공방법에 관한 것으로서, 상기 듀얼-프리스트레싱 강합성빔은 절곡 하부플랜지에 일체화된 하부케이싱블록과 강재빔 상면에 설치된 상부압착강재를 포함한다.
