A simply supported 20 m effective span RCC rectangular beam 600 mm x 1500 mm is reinforced throughout with 21-25 mm bars in three layers of 7 bars in each layer at a clear cover of 40 mm to tensile reinforcement. The reinforcement in compression face is 5-25 mm bars in one layer at an effective cover of 50 mm. The clear cover between the different layers on tension face is 25 mm. What is the maximum bending moment at the limit state of collapse (in kNm)? [Take fsc = 0.8f, M25 grade concrete, Fe415 grade steel]
