Civil Engineering QUESTION #6589
Question 1
In a reinforced concrete member under applied loading, if the steel reaches its maximum (yield) stress before the concrete reaches its limiting compressive strain, the section is classified as:
  • Over-reinforced section
  • Balanced section
  • Under-reinforced section✔️
  • None of the above
Correct Answer Explanation
An under-reinforced section has less steel than the balanced condition. Steel yields first, providing ductile failure with large deflections as warning before the concrete crushes.
