BEHAVIOR OF ANCHORED BARS UNDER LOW CYCLE OVERLOADS PRODUCING INELASTIC STRAINS

THE BEHAVIOR OF ANCHORED BARS SUPPORTING CANTILEVER BEAMS WAS STUDIED. THE BARS WERE INTENDED TO SIMULATE THE ANCHORAGE CONDITIONS AT AN EXTERIOR BEAM-COLUMN JOINT WHERE THE BEAM IS SUBJECTED TO LARGE CYCLIC OVERLOADS WELL INTO THE YIELD RANGE OF THE REINFORCEMENT. TWENTY SPECIMENS WERE TESTED UNDER MONOTONIC, REPEATED, OR REVERSED LOAD CYCLES TO FAILURE. THE INFLUENCE OF LOAD HISTORY AND BEAM GEOMETRY ON STRESSES ALONG THE BAR AND ON ELONGATION OF THE BAR WAS STUDIED. THE RESULTS INDICATE THAT UNDER REPEATED OR MONOTONIC LOADS, STRESSES AND ELONGATIONS GRADUALLY INCREASED WITH INCREASING END DEFLECTIONS. UNDER REVERSED LOAD, STRESS DISTRIBUTIONS DID NOT CHANGE SIGNIFICANTLY BUT ELONGATIONS INCREASED CONSIDERABLY.
