If the depth of actual neutral axis in a beam is more than the depth of balanced neutral axis, then the beam is called as
- ABalanced beam
- BOver reinforced beamCorrect
- CUnder Reinforced beam
- DPartially reinforced beam
Solution
Concept
Over-reinforced section
Formula
xu > xu,max
Step-by-step solution
1. xu > xu,max means the steel is under-stressed and concrete crushes first. 2. Such a beam is over-reinforced.
Explanation
A deeper neutral axis implies more tension steel than the balanced section.
Why the other options are wrong
Under-reinforced has xu < xu,max; balanced has xu = xu,max.
Shortcut
xu larger than limiting = over-reinforced.
Correct answer: B) Over reinforced beam
