THE CONTINUOUS BRIDGE STRUCTURE INCLUDING A PRESTRESSING PLATE AND IT'S BUILDING METHOD

摘要

A continuous support structure including a prestressing steel plate and the construction method thereof are provided to increase the effective cross section of a continuous support and to decrease the negative moment of a continuous support by applying compressive stress on a continuous support with a prestressing steel plate. A continuous support structure includes a girder(100) installed on a continuous support located on an abutment or a pier of a steel bridge, a slab(200) formed on the top of the girder with concrete, an anchor bolt(600) fixed to the girder, and a prestressing steel plate(500) fastened to the anchor bolt and prestressing the steel bridge, wherein the cross section of the lower part of the prestressing steel plate becomes the effective cross section of the continuous support of the steel bridge.
