New findings on the fatigue behavior of precast elements

Behavior of prestressed concrete girders

For prestressed precast concrete elements used in structures with predominantly cyclic loading, for example craneway girders in industrial structures or precast girders in bridge constructions, design and construction against fatigue is of crucial significance. The fatigue life of prestressed precast elements depends primarily on the fatigue strength of the prestressing steel reinforcement, which is influenced by many structural and load specific factors. These include the degree of prestress and the degree of longitudinal reinforcement as well as the loading level and the amplitude. These...
