INFLUENCE OF THE GRADE OF PRESTRESSING IN RELATION TO THE MATERIAL ECONOMY OF THE CONSTRUCTION OF RAILWAY BRIDGES

At the German State Railway (DR) the bridges from prestressed concrete are calculated with full prestressing. In the paper presented, the possibilities to economize prestressing steel by variation of the grade of prestressing, which were ascertained by comparison calculations, are described. Proposals are made to calculate prefabricated superstructures for railway bridges with limited or partial prestressing in dependence of the kind of loading. The safety and the durability of the bridges are not impaired in this manner.
