STEEL BOX GIRDER ASSEMBLY HAVING MEANS TO PULL PRESTRESSED WIRES AND METHOD FOR CONSTRUCTING BRIDGE HAVING THE STEEL BOX GIRDER
The present invention relates to a steel box girder assembly having a means to pull prestressed wires, capable of easily adjusting and offsetting shear stress and bending moment acting on a bridge by including a means to easily pull prestressed wires. The steel box girder assembly having a means to pull prestressed wires according to the present invention comprises: a steel box girder; a prestressed wire whose both ends are fixated to an upper portion of both end portions of the steel box girder, and whose central portion in the longitudinal direction is arranged to extend downward; and a prestressed wire pulling means for pulling the prestressed wire so that the central portion of the prestressed wire gets closer to a lower flange of the steel box girder. In addition, the present invention relates to a method for constructing a steel composite bridge by using the steel box girder assembly having the means to pull prestressed wires.
