Problem 2 Design a rectangular reinforced concrete beam to resist a total design moment Mu of 765 ft-kips (this includes moment due to the weight of the beam). The beam size is limited to 15 in. maximum width and 30 in. maximum overall depth. Use fc,-3000 psi and/S-60,000 psi. If compression steel is required, make d'-2.5 in.

Figure 3 shows the cross-section of a reinforced concrete beam which incorporates a services duct on the compression side. The concrete has the following properties: f'c =32 MPa, y = 0.82, and Ec = 28,500 MPa. Calculate the ultimate moment, Mu, for this section from first principles. Please note that the reinforcement yield stress for this question is 460 MPa and Ast = 4800mm. You may use the usual equivalent rectangular stress block and the limiting strain criterion (EU =...
