compression reinforcement. Calculate the nominal moment capacity Mn and
indicate if the beam has adequate capacity to resist a factored moment Mu of
400 kip ft. Indicate whether the beam meets code requirements for minimum
The beam has 6 No. 9 bars for tension reinforcement and 2 No. 5 bars for
and maximum amounts of reinforcement.
