Under reinforced is that in which provided steel ratio is less than balanced steel ratio. Concrete beams are designed as under reinforced beams. The reason is that the failure start by yielding of steel instead of crushing of concrete.

What does steel stirrup do in reinforced concrete beam and column?
It proves shear reinforcement in the beam.
In which situation doubly reinforced beams used?
when our demand is more than capacity then designer prefers to choose doubly reinforced beam .for example your maximum moment is greater than nominal momentthen doubly reinforced beam is used.
What does stirrup do to reinforced concrete beam?
to resist shear force
What is the concrete coverage for a reinforced beam?
25 mm cover should be given
What is the difference Between under reinforced section and over reinforced section?
When the maximum stresses in steel and concrete simultaniously reaches allowable value the section is called balanced section when the %of steel in a section is less than that required for a balanced section it is under reinforced section when the %of steel in a section is more than that required for a balanced section it is over reinforced sectionover reinforcement is as per section design I.e Ast1+Ast2>Ast Ast1+Ast2
What is the advantage and disadvantage of reinforced concrete beam and column?
reinforced concrete prise
What does steel stirrup do in reinforced concrete beam and column?

What does stirrup do to reinforced concrete beam?
to resist shear force
How is Reinforced concrete made?
Reinforced concrete is made by placing steel bars in the tension zone of the beam x-section.
What is the effective depth of reinforced rectangular beam?
Total Depth - cover
How Reinforced concrete floor beam built?
because of the cement that can hold them tightly
What is the minimum compression reinforcement to be provided in singly reinforced beam?
3000 psi
What is the concrete coverage for a reinforced beam?
25 mm cover should be given
What is the difference between the singly reinforced beam and doubly reinforced beam?
A singly reinforced beam only has steel reinforcement on the tension side (along the bottom of the cross section) where as a doubly reinforced beam has steel reinforcement on both the tension and compression sides, ie. the top and bottom of the cross section.
What is the difference Between under reinforced section and over reinforced section?
When the maximum stresses in steel and concrete simultaniously reaches allowable value the section is called balanced section when the %of steel in a section is less than that required for a balanced section it is under reinforced section when the %of steel in a section is more than that required for a balanced section it is over reinforced sectionover reinforcement is as per section design I.e Ast1+Ast2>Ast Ast1+Ast2
