A rectangular beam has a width of 300 mm and an effective depth of 510 mm. It carries Vu = 200 KN and Mu = 55 KN-m and is reinforced with 2650 mm2. Use f’c = 21 MPa and fy = 345 MPa. Normal concrete. Express your answer in two decimal places.
a. Compute the shear strength in KN provided by concrete using the less conservative formula as shown. Express your answer in two decimal places.
b. Calculate the required area of compression reinforcement in mm2 due to the factored moment, Mu.
