Study on the PC Beam for Extradosed Prestressed Bridges


Article Preview

This paper is described about the research work on the PC beam for extradosed prestressed bridges. After summing up domestic extradosed prestressed bridges with PC beam, we recommended that the PC beam should be more diversity and creative. We have drown some conclusions through the numerical analysis and reduced scale prototype model test for Jiayue Bridge in Chongqing China, this bridge has double-cable-plane, and the PC beam’s broad flange is 8m. Finally, we suggested that further research on the PC beam of extradosed prestressed bridges should focus on the phenomenon of shear lag and extra-prestressing, etc.
