Abstract: In R.C rectangular beams, theoretically there is no effect of curtailment of steel in flexure. The objective of this work is to establish Load vs Deflection and Load Vs Crack width relationships for RC beams with same Ast but with and without curtailment of tension reinforcement. An experimental study was conducted on 2 RCC beams of 0.23 m x 0.23 m x 1.5 m size with same Astcorresponding to Moment of Resistance of 40 kN_m. From the study, it was observed that curtailment improved the Moment carrying capacity and displacement ductility.

Keywords: Curtailment, Area of tension steel, Moment of resistance, deflection, crack width.
