Question

Flexural collapse in over reinforced beam is due to

Answer 1

Due to the Secondary compression failure, in over reinforced beam the flexural collapse is happened.

Explanation:

• To look after the secondary compression failure when concrete reinforcement is done.
• During the Beam construction, flexural collapse is not a collapse that occurs due to Steel.
• In the case of secondary compression failure, the Steel remains as it is there is no failure of Steel.
• With the main Failure, the concrete damage or breaking of concrete that happens due to increased strain.
• On The Beam, which is more than the prescribed limit and hence flexural collapse occurs.

Answer 2

Flexural Collapse in over reinforced beam occurs due to compression failure.

What is over reinforced beam?

When the strain of the concrete reached failure before the strain of steel reached yield and there occurs a maximal allowable stress in concrete prior to steel, it is called over reinforced beam.

In over reinforced beam, Flexural collapse is due to:

• When stress in concrete reaches its acceptable limit before steel, there is sudden collapse in the structure of the beam.
• There occurs a failure in over reinforced beam called compression failure because crushing of concrete occur before producing tension reinforcement.

Thus, there occurs a compression failure when concrete first fail in compression and then steel.
