FATIGUE STRENGTH IN SHEAR OF PRESTRESSED CONCRETE 1-BEAMS
THE RESULTS OF STATIC AND REPEATED LOAD SHEAR TESTS ON 17 POST-TENSIONED I-BEAMS, WITH WEB REINFORCEMENT, ARE PRESENTED. THE EFFECT OF FATIGUE ON THE DIAGONAL CRACKING STRENGTH AND THE EFFECT OF A LOAD HISTORY ON THE SUBSEQUENT STATIC DIAGONAL CRACKING STRENGTH IS REPORTED. THE CRITERION OF FATIGUE FAILURE, IN ALL CASES, WAS FOUND TO BE STIRRUP FRACTURE. THE NUMBER OF CYCLES TO FIRST STIRRUP FRACTURE AND THE NUMBER OF CYCLES TO COMPLETE BEAM FAILURE ARE GIVEN FOR THREE MAXIMUM LOAD VALUES. THE MINIMUM LOAD WAS CONSTANT IN ALL TESTS. THE RESULTS ARE SUMMARIZED IN THE FORM OF STRESS CYCLES-PROBABILITY CURVES. /AUTHOR/
