This set of Design of RC Structures Multiple Choice Questions & Answers (MCQs) focuses on “Shear in Beams – Diagonal Tension”.
1. What should be the maximum moisture content for the bulking in sand?
a) 4%
b) 6%
c) 8%
d) 10%
View Answer
Explanation: According to the codes of Indian Standards moisture should be 4% for bulking in sand.
2. Diagonal Tension in beam is ______
a) Increases below the neutral axis and decreases above the neutral axis.
b) Remains same
c) Change according to the condition
d) Can’t be justified
View Answer
Explanation: Diagonal tension depends on sagging, hogging and load nature.
3. Which of the following is directly proportional to workability of concrete?
a) Cement content
b) Time
c) Grade of aggregate
d) Sand
View Answer
Explanation: Grade of the aggregate affects the workability as the grade increase its workability increases.
4. Why is shear reinforcement provided in concrete?
a) To resist vertical shear
b) To resist diagonal tension
c) To resist horizontal shear
d) To resist diagonal compression
View Answer
Explanation: Shear reinforcement is provided in concrete to resist diagonal tension as diagonal tension is the main reason for the failure in concrete.
5. What should be the minimum head over the stairs?
a) 210 cm
b) 220 cm
c) 230 cm
d) 240 cm
View Answer
Explanation: According to Stair Code: R311.5.3.1 the minimum head should be 210 cm.
6. What is the young’s modulus for elasticity?
a) 150kN/m2
b) 200kN/m2
c) 250kN/m2
d) 275kN/m2
View Answer
Explanation: Young’s modulus is stress/strain.
7. What is the horizontal portion of step in staircase called?
a) Tread
b) Rise
c) Winder
d) Flight
View Answer
Explanation: Horizontal portion of step is called tread and vertical is called rise.
8. What is the usual angle at which bar is bent to provide diagonal tension?
a) 30°
b) 40°
c) 45°
d) 60°
View Answer
Explanation: Bars can be bent only if the remaining bars are sufficient to resist the prevailing bending moments.
9. For single bars, all bent up are provided differently in a group.
a) True
b) False
View Answer
Explanation: For single bars or group of parallel bars, all bent up are provided at same crossection.
