A two-span railway bridge is processed as a prestressed concrete box girder. Tendons with post-tensioned are arranged in both webs. The traffic load is considered only as a simplified uniform distributed load for the better overview of this example. It is shown the checks at serviceability limit state, the checks at alternate limit state as well as the checks at safety against cracking. The maximum stresses which occur are represented graphically in the longitudinal direction of the box girder.
