Q1:

A simply supported beam shall be deemed to be a deep beam if the ratio of its effective span to overall depth, is

A 2.0

B 2.5

C less than 2

D less than 2.5

ANS:A - 2.0

Beams with large depths in relation to spans are called deep beams.

As per IS-456 (2000) Clause 29, a simply supported beam is classified as deep when the ratio of its effective span L to overall depth D is less than 2.

Continuous beams are considered as deep when the ratio L/D is less than 2.5.
