The paper presents experimental work done to understand effect of bar diameter and placement of tension reinforcement on flexure behavior of simply supported beams. Eight beam of 150×250×1500 of M25 grade of concrete and Fe415 grade of steel were cast and subjected to two point load flexure test under universal testing machine as specified in IS516. Deflection was measured at the centre point and at the point of application of load with the dial gauge, to enable load v/s deflection plot. Experimental result indicate that a small change in area of steel and placement of reinforcement place a very vital role in deflection and ultimate load carrying capacity.

Keywords: Limit state method, working stress method, under reinforced section, deflection, ultimate load.
