SHEAR BEHAVIOUR OF REINFORCED NORMAL WEIGHT CONCRETE DEEP BEAMS USING FINITE ELEMENT ANALYSIS

Abstract

The shear behaviour of structural elements, particularly deep beams has been an area of huge concern in the structural engineering community. This study investigates the shear behaviour of deep reinforced concrete beams by presenting and evaluating results of experimentally tested beams to their corresponding finite element models. By using ANSYS, the finite element computational platform, a validated model is presented for three deep reinforced concrete beams that were cast and tested in the laboratory. Their load-deflection responses were compared. The failure modes, as well as the cracking behaviour of the models were also analyzed. It was observed that the load-deflection behaviour from the finite element analysis correlate very well with that of the experimentally tested beams. Furthermore, the finite element analysis was found out to mimic the cracking behaviour. It also predicted the failure mode and ultimate failure loads of tested beam appropriately
