Question: a reinforced concrete member with a reinforcement ratio ...

A reinforced concrete member with a reinforcement ratio ρ = area of steel/total area of reinforced concrete member. If plain concrete shrinkage strain is εsh, and compressive strength = f’c, what is the resultant shrinkage strain of the member and the stresses in concrete and steel for the following cases:

a) ρ = 1%, εsh = 0.06%, f’c = 4,000 psi, b) ρ = 1%, εsh = 0.1%, f’c = 4,000 psi, c) ρ = 0.5%, εsh = 0.06%, f’c = 4,000 psi, d) ρ = 1%, εsh = 0.06%, f’c = 5,000 psi.
