2. A R.C. beam 300×600 mm (overall) is reinforced with 4-250 bars at bottom and 2- 200 bars at top, each at an effective cover of 40 mm. Find the ultimate moment of resistance of the beam. What alteration in the quantity of tensile steel is necessary to make it a balanced, doubly reinforced beam and what will then be its ultimate moment of resistance? Consider M15 grade concrete and Fe250 grade steel. 2. A R.C. beam 300×600 mm (overall) is reinforced with 4-250 bars at bottom and 2- 200 bars at top, each at an effective cover of 40 mm.
