Structural Analysis

Givens:

Concrete beam: Rectangular

Fy= 75k psi

Concrete Strength (f'c)= 5k psi

Clear cover = 1.5'

Stirrups=#4

Compression Reinforcement= (4) #9

Tension Reinforcement= (4) #9

Beam Height (h)=4'

Beam width (b)=2'

Question: Is the grade of steel sufficient to be used as a stirrup? (Web Shear Reinforcement) why or why not? Please explain your reasoning and show all calculations.
