Civil Engineering QUESTION #6653
Question 1
What happens if a RC beam is 'Over-reinforced'?
  • The steel yields before the concrete crushes
  • The concrete crushes before the steel yields✔️
  • The beam will never fail
  • The deflection will be very large before failure
Correct Answer Explanation
An over-reinforced beam fails suddenly (brittle failure) because the concrete reaches its compressive limit while the steel is still in the elastic range.
