Abstract
A PSSC complex girder in which a section shape steel structure is formed by joining one or more section shape steel. The PSSC complex girder includes a tension means for tensioning the section shape steel structure with a tensional member so that the structure has a predetermined camber. Concrete is poured in an inner space portion of the section shape steel structure. A strengthening plate for supporting buckling and compression is joined to the section shape steel. A sheer prevention member and steel reinforcement are joined to the section shape steel and the concrete is poured therein. The camber of the PSSC complex girder can be adjusted before or after construction for new bridges and conventional bridges. Deflection of the slab can be easily decreased and cracks caused by flexural deformation can be prevented.
