This set of Design of RC Structures Multiple Choice Questions & Answers (MCQs) focuses on “Shear in Beams – Inclined or Diagonal Reinforcement”.
1. Why is shear reinforcement in RCC provided?
a) To resist vertical shear
b) To resist horizontal shear
c) To resist diagonal compression
d) To resist diagonal tension
View Answer
Explanation: Shear resists diagonal failure so the shear reinforcement is provided to resist diagonal tension.
2. The angle by which bars are bent at horizontal in degree is ____
a) 30
b) 45
c) 60
d) 90
View Answer
Explanation: When inclined reinforcement is provided, they consist of main tension reinforcement bent up at 45°.
3. The compressive strength of concrete is about 10 -20% of its tensile strength.
a) True
b) False
View Answer
Explanation: The compressive strength of concrete is more than its tensile strength.
4. Where is steel provided in singly reinforced beams?
a) Tension Zone
b) Compression Zone
c) Both the zones
d) Steel is not provided at all
View Answer
Explanation: Load in singly reinforced beam is exerted at tension so it is provided in tension zone.
5. Where is steel placed in simply supported beams?
a) Above neutral axis
b) Below neutral axis
c) At the neutral axis
d) Anywhere
View Answer
Explanation: Load is exerted below the neutral axis in simply supported beam so reinforcement is also applied there.
6. The most effective method for designing beams is _______
a) Ultimate load method
b) Limit state method
c) Working stress method
d) Any of these
View Answer
Explanation: Limit state method is the most cost effective and exact method for designing RC structures.
7. If load is very small in singly reinforced beam than ______
a) Both concrete and steel will resist tension
b) Both concrete and steel will resist compression
c) Only concrete will resist compression
d) Only steel will resist tension
View Answer
Explanation: Since the load is very small and concrete also has very low amount of tensile strength so both will resist tension.
8. The no. of treads in a flight is _____
a) Riser + 1
b) Riser – 1
c) Riser
d) Riser / 2
View Answer
Explanation: Treads in the flight is always one less than riser.
9. Maximum area for tensile reinforcement in a beam is _____
a) 2%
b) 4%
c) 5%
d) 10%
View Answer
Explanation: If the tensile reinforcement will exceed from 10% than compressive strength will become low because of less concrete.
10. Thick part of flat slab over the column is called _______
a) Capital
b) Drop Panel
c) Column Head
d) Beam
View Answer
Explanation: Thick part is known as drop panel and column head is present at the base of it.
