CREEP AND SHRINKAGE IN REINFORCED CONCRETE BEAMS

AN ANALYSIS IS MADE OF CREEP AND SHRINKAGE EFFECTS IN A CRACKED RECTANGULAR CONCRETE SECTION CONTAINING BOTH TENSION AND COMPRESSION REINFORCEMENT AND SUBJECTED TO A CONSTANT SUSTAINED MOMENT. RESULTS ARE CHECKED FOR ACCURACY AGAINST PUBLISHED TEST DATA. CALCULATIONS OF LONG-TERM BEAM BEHAVIOR SHOW AN EXTREME REDISTRIBUTION OF INTERNAL STRESSES IN THE SECTION. IN SOME NOT UNUSUAL CASES IT IS SHOWN THAT TENSILE STRESSES CAN APPEAR IN THE UPPER COMPRESSIVE FIBERS OF THE CONCRETE. THE ANALYSIS PROVIDES A MEANS FOR INVESTIGATING LONG-TERM DEFLECTIONS IN REINFORCED CONCRETE BEAMS. /ASCE/
