1. A simply supported concrete beam having a width of 350 mm and an effective depth of 520 mm carries a uniformly distributed factored of load (including its own weight) of 7 kN/m and a concentrated load Pu acting 2 meters from the left support. Use 2 = 1.0. f'c = 20.7 MPa, fy = 415 MPa for both main reinforcements and stirrups. (60 Points) 370 kN 2m 7 kN/m C 3 m a. Compute the maximum factored shear force Vu at the critical section from support A. b. Compute for the shear contribution of concrete, Vc c. Is shear reinforcement required? Prove your answer. d. Compute for Vs if shear reinforcement is required. e. What is the maximum allowed shear contribution of stirrups? f. Determine the maximum allowed spacing of stirrups using 10 mm diameter ties.
