Abstract
An upper structure for a bridge includes a coping placed on the top end of a pier, and a girder held by the coping, wherein a side surface of the coping and an end surface of the girder are configured as inclined surfaces (or vertical surfaces), wherein a shear key protrudes on one of the inclined surfaces (or vertical surfaces), and a shear key slot is formed in another one of the inclined surfaces (or vertical surfaces) so as to be engaged with the shear key. The present disclosure can reduce the construction cost, can realize improved structural efficiency of the bridge upper structure, can realize an easy installation of the girders, can easily combine the girders with the coping without plastering or fixing with mortar by site work, and can efficiently resist to a shear stress that may be generated in the bridge.
