QUESTION 01. Figure 1 shows a simply supported beam and the cross-section at midspan. The beam supports a uniform service (unfactored) dead load consisting of its own weight plus 20 kN/m and a uniform service (unfactored) live load of 22 kN/n. The concrete strength is 24 MPa, and the yield strength of the reinforcement is 420 MPa. The concrete is normal-weight concrete. Use load increment and strength reduction factors from ACI Code sections 9.2 and 9.3 (i.e. 1.2 wa; 1.6w and q= 0.9). For the midspan section shown in part (b) of Fig. 1, compute oM, and show that it exceeds M,. WD = WL = 20 kN/m plus weight of beam 22 kN/m 550 600 A, =3 HD25
