Abstract

The finite element model of a prestressed concrete box-girder bridge was established,then the numerical simulation were carried out under the conditions of vertical temperature gradient. The effect of vertical temperature gradient is the important reason for the concrete cracks of box girder, and the loss of vertical prestressit has important influence to longitudinal stress of box girder.
