CONSTITUTION: A method for manufacturing an arch-shaped composite girder bridge through the separated concrete filling in a girder is as follows. A girder is manufactured in a construction site using girder outer steel(210). The girder is filled with concrete through several times. A tendon is installed in the girder and tenses the girder one time(250). The girder is transferred to a bridge construction position and is installed in an abutment or a pier. Concrete and slab concrete are simultaneously placed in the center of the girder(270).

Abstract: PURPOSE: A high-toughness precast girder made with high-toughness concrete and a bridge construction method using the same are provided to secure earthquake-resistant performance and ductility through integral movement of the inner concrete. CONSTITUTION: A high-toughness precast girder made with high-toughness concrete comprises a concrete form, inner concrete(200), and a shear connection part. The concrete form is made with high-toughness concrete including steel fiber or organic fiber. The inner concrete is filled in the concrete form and formed into one body. The shear connection part in which steel reinforcements arranged in the concrete form are projected inward is formed between the concrete form and the inner concrete.

Abstract: PURPOSE: A tide arch shaped composite girder bridge connected by precast blocks and a construction method are provided to improve workability and construction performance by reducing the time for a bridge construction. CONSTITUTION: A tide arch shaped composite girder bridge connected by precast blocks comprises a plurality of girder segments(10a,10b,10c), a shear key part, inner tendons, and outer tendons(30). The girder segments are divided by filling girder concrete(14) in an outer steel(12), and are connected with the girder concrete and a steel material in a site. The shear key part formed in a joint surface of the girder concrete resists shear force. The inner tendons inserted into the upper end of the girder segments provide tensile force by initial compressive stress. The outer tendons inserted in the bottom end of the girder segments provide tensile force.

Abstract: A prestressed concrete box girder bridge having struts is provided to reduce the dead weight of an upper structure of a bridge by optimizing the cross section of a bridge girder, and to secure an open view at the lower part of the bridge by downscaling a pier and reducing the number of piers installed. In a prestressed concrete box girder(1), two box openings(2) are formed by a side wall(5) and a partition wall(3), cantilevers(4) projected to two sides, and struts(10) are arranged at regular intervals to support and reinforce the cantilevers. The struts are manufactured with FRP(fiber reinforced plastic) reinforced concrete beams and installed to be inclined between the bottom of the cantilever and the side wall of the box opening and arranged at regular intervals in the longitudinal direction of a bridge to support.
