Per ACI 10.7.1, a beam is considered to be a deep beam for flexural design if the overall section depth to clear span ratio is greater than 0.4. In this case, a design warning will be provided. The check is performed assuming that the beam is part of a continuous beam line. The program does not currently implement the remaining sections of ACI 10.7. It is the engineer's responsibility to provide adequate reinforcement to satisfy ACI 10.7.2 through 10.7.4.
