BOND DETERIORATION IN REINFORCED CONCRETE SUBJECT TO LOW CYCLE LOADS

THE INFLUENCE OF LOAD HISTORY ON THE DETERIORATION OF BOND ALONG BARS SUBJECTED TO ELASTIC STRESSES WAS STUDIED EXPERIMENTALLY. TWO TYPES OF SPECIMENS WERE USED. ONE SERIES CONSISTED OF AXIALLY REINFORCED PRISMS SUBJECTED TO ALTERNATING LOADS. IN THE SECOND SERIES, STRESS TRANSFER ALONG BARS ANCHORED TO SUPPORT A CANTILEVER BEAM WAS STUDIED. CYCLIC LOAD WERE IMPOSED ON THE BEAM. THE RESULTS INDICATE THAT THE MOST IMPORTANT FACTOR AFFECTING BOND OR STRESS TRANSFER IS THE PEAK STRESS REACHED IN PREVIOUS CYCLES. REPETITIONS OF LOAD CYCLES WITH CONSTANT PEAK STRESS PRODUCED ONLY A GRADUAL DETERIORATION OF STRESS TRANSFER CAPACITY. /AUTHOR/
