PROBLEM TO BE SOLVED: To secure high-strength bending resistance, shear resistance, and an axial force between girder ends of left span main girders and right span main girders.;SOLUTION: According to the continuous girder structure of the multispan girder bridge, girder ends 3a of a plurality of the left span main girders 3 and the girder ends 3a of the right span main girders 3 are borne to a common pier 2, and a span complementary girder 5 is arranged so as to extend between side surfaces of the girder ends 3a of the left span main girders 3 and side surfaces of the girder ends 3a of the right span main girders 3, and the girder ends 3a of the left span main girders 3, the girder ends 3a of the right span main girders 3, and the span complementary girder 5 are embedded in a connecting concrete slab 7 formed by placing concrete on the pier 2, to thereby connect both the girder ends 3a to each other.;COPYRIGHT: (C)2007,JPO&INPIT
