USING ACI 318 Codes

Problem #3: Design the RC beam given the information below. Ensure that the reinforcement fits in the section, and that the section is tension controlled (i.e., phi = 0.90). Simply supported 20 ft beam.

w = 1 kip/ft (dead, does not include self-weight), 1.5 kip/ft (live); f'c = 5,000 psi; fy = 60 ksi; b = 14"; d = 28"; #3 Transverse Reinforcement.

Problem #4: Given the same information above, however Mu = 360 kip-ft; b and d are now unknown. Assume that 1.2D + 1.6L is the controlling load condition. Design the RC beam, and ensure that the reinforcement fits and that the section is tension controlled. Mu does not include the beam self-weight.
