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.

Abstract: A concrete composite structure of a double cross section using a precast inner composite block segment, and a construction method of the concrete composite structure are provided to secure the connection efficiency sufficiently by connecting pipe-shaped fiber reinforced plastics mutually, to minimize the work in a construction site, to utilize a precast product manufactured in a factory to the maximum, and to have excellent economical efficiency, constructability and durability by making conveyance and installation possible. A concrete composite structure of a double cross section comprises a support structure, an inner composite block(200), and an outer block. The support structure is provided with many reinforcing bars and supported by installing the inner composite block and the outer block in a double cross-sectional structure, wherein a connection member including a reinforcing bar and a reinforcing bar assembly to connect with the inner composite block structurally. The inner composite block is manufactured at the appointed height by connecting precast inner composite block segments(200a,200b,200c) having a hollow(S) vertically in order, and placing plain concrete(221a,221b,221c,221d) in the inside of the precast inner composite block segments, wherein a ductility securing member(230) including a reinforcing bar or a reinforcing bar assembly is installed over the entire length of the inner composite block on the inside of precast concrete(220a,220b,220c,220d) of the inner composite block to secure ductility. The outer block is installed to cover the inner composite block and made of fiber reinforced plastics to secure the structural safety of a connection.
