To provide a girder end structure which dispenses with a sole plate wherein, in the case of a composite girder prepared by combining a steel member with concrete, a steel plate is used for a lower flange and the sole plate needs to be installed in order to secure the flatness of the lower flange in supporting a girder end by a support for avoiding an increse in machining cost and installation cost.
A concrete upper flange 4 provided at the upper end of a steel web 2 is projected further upper than ends of the steel web 2 and the steel lower flange 3 fitted to the lower end of the steel web, a concrete support end 5 is formed at the lower part of the projecting part, and the support end 5 is placed in the support part of a pier bringing the lower flange 3 into a state that the lower flange 3 is not placed in the support part. A plurality of composite girders 1 are extended over the piers, concrete members 7, 9 are provided at an intermediate part of the support end 5 and an intermediate part of the upper flange 4, and a PC steel member 8 is inserted in the right-angled direction with respect to a bridge axis to introduce prestress.
