Research abstract
PREDICTING THE BEHAVIOR OF REINFORCED CONCRETE STRUCTURES SUBJECTED TO BLAST LOADING UNDER WEAPONS EFFECTS IS OF INTEREST. THE MODELING TECHNIQUES DEVELOPED USING FINITE ELEMENT METHOD ALLOWS CONCRETE TO DEFORM/CRACK. HOWEVER, THE BEHAVIOR OF THESE CRACKED BLOCKS AND THE BREAK-UP AND SPALLING OF CONCRETE CAN'T BE PREDICTED BY THESE TECHNIQUES. THE DISCRETE ELEMENT METHOD ALLOWS CONCRETE TO CRACK AND THE BLOCKS TO SEPARATE/SPLIT INTO INDIVIDUAL ELEMENTS ACTING AS RIGID BODIES PERMITTING TO PREDICT MORE REALISTICALLY THE BEHAVIOR OF THE STRUCTURE AT FAILURE. THE OBJECTIVE OF THIS RESEARCH IS TO DEVELOP AN ANALYTICAL MODELING USING DEM FOR REINFORCED CONCRETE TO PREDICT THE BEHAVIOR OF THE STRUCTURE AT FAILURE.
