NUMERICAL ANALYSIS OF VOIDED WIDE REINFORCED CONCRETE BEAMS USING STEEL PLATES FOR SHEAR REINFORCEMENT

The present paper intended to investigate the impact of the parametric study of wide reinforced concrete beams that used steel plates as shear reinforcement. The researcher used ANSYS software version 16.0 to analyse the flexural performance of the beam specimens. All the beams were 560 mm width and 215 mm height. The effective depth of the beam is 170 mm. These parameters included effect of concrete compressive strength, type of loading, shear span to effective depth ratio and thickness of steel plates. The selected values of compressive strength were 25 and 50 MPa with the experimental load deflection curves fc` = 33 Mpa. The values of shear span to effective depth ratio were 2 and 1.5 with the experimental value 3.53. The thickness of shear steel plates was 4 mm and 5 mm with the experimental thickness 3 mm. The obtained results of the present study have come conforming to the results of the experimental one. Increasing the concretes compressive strength, the ultimate load increases by 5.13%. Also state that ultimate load increase by 7.71% when applied two points loads on beams. The ultimate load of reinforced concrete beams with steel plates increased by 16.68% and 33.06% when a /d decrease to 2 and 1.5 respectively. Also, the ultimate load increased by 3.67% and 10.24% when thickness of steel plates increased to 4 mm and 5 mm respectively.
