Problem (2) Design the tension reinforcement for the following doubly reinforced beam.Compressive strength of concrete is 5000 psi . Yield strength of steel is \( 40,000 \mathrm{psi} \) for both tension and compression reinforcement. Width = 16 in. Thickness = 30 in. Effective depth for tension steel = 27 in. Effective depth for compression steel = 3 in. Compression steel: 2 - \# 9 bars placed in single layer. Ultimate moment = 4,950,000 in-lb. Use \# 9 bars for tension reinforcement.
