When the problem statement highlights over-reinforced flexural behaviour, which response is technically correct? Avoid the common trap that larger steel area always increases ductility.
Choose the correct answer
neutral axis has no relation to steel percentage
larger steel area always increases ductility
larger steel area pushes neutral axis deeper and may cause brittle compression failure
neutral axis is fixed by span only
Correct Answer
C. larger steel area pushes neutral axis deeper and may cause brittle compression failure
