4. Analyze the beam shown below given fe' = 3500 psi and fy= 60,000 psi:
(a) Use d = 22 in. (effective depth of tension reinforcement), assuming the compression steel
yields at the ultimate stage, calculate the reinforcing ratio of flexural reinforcement.
(b) Is the beam underreinforced or overreinforced? Show reasons to your answer.
(c) Calculate the nominal flexural strength of the section: M,?
(d) Determine the design capacity of the section: øMn.
