Abstract
In 2008 Nepal earthquake, in a bridge was developed crack in girder. Displacement of the girder was also cause of earthquake. In bridge study earthquake motions records from close to the bridge site and motions inputs for the bridge’s time history analysis. Stresses of the girder are taken into account in the bridge model. Crack process and affects of crack held in discussion. For high stress zone different seismic inputs are taken. The result show that fracture develop when the girder’s tensile stress surpasses concrete tensile strength during earthquake excitations.
