Abstract:
ified. Experimental data on the fatigue life of prestressing strands are compared with data on the fatigue life of partially prestressed beams. A close correlation results of a reliability based models of partially prestressed beams in which serviceability and ultimate strength limit states is observed. Global were considered, are presented. They strongly suggest that fatigue in the reinforcement is a controlling limit state that must be seriously accounted for in design.
