A rectangular concrete beam has a width of 300 mm and an effective depth of 550 mm. The beam is simply supported over a span of 6 m and is used to carry a uniform dead load of 25 KN/m and a uniform live load of 40 kN/m. Assume fic= 21 MPa and fx = 312 MPa. Compression reinforcement if necessary shall be placed at a depth of 80 mm from the extreme compression concrete.Which of the following most nearly gives the required number of 25mm diameter tension bars?A. 6 B.7 C. 8 D. 9
