This set of Design of RC Structures Multiple Choice Questions & Answers (MCQs) focuses on “Bonds – Curtailment of Reinforcement”.
1. What is the correct formula for section modulus?
a) I/y
b) I.y
c) y/I
d) 2I/y
View Answer
Explanation: Section modulus is denoted by z and in the formula, ‘I’ stands for moment of inertia and y stands for distance from neutral axis.
2. Where will be the maximum tensile stress at the simply supported beam having UDL at total span?
a) Neutral Axis
b) Top Fiber
c) Bottom Fiber
d) Conditions are not enough to determine
View Answer
Explanation: At bottom fiber, there is maximum stress because the maximum loading is transferred to the bottom axis of the beam.
3. What will be the result of failure in the concrete block?
a) Diagonal Tension
b) Bottom Failure
c) Shear
d) Creep
View Answer
Explanation: Concrete is 10 times stronger in compression than steel, hence if a concrete block is subjected to shear stress it may result to diagonal tension.
4. 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.
5. Which of the following is directly related to workability of concrete?
a) Cement
b) Aggregate–Cement Ratio
c) Grade of Aggregate
d) Transit
View Answer
Explanation: Grade of the aggregate and workability of concrete is directly proportional to each other.
6. What is the modulus of elasticity for steel?
a) 100kN/mm2
b) 200N/mm2
c) 200kN/mm2
d) 200kN/cm2
View Answer
Explanation: According to Code IS 456:2000, the modulus of elasticity for steel is taken as 200kN/mm2.
7. What is the heaviest I section beam?
a) ISHB
b) ISLB
c) ISMB
d) ISWB
View Answer
Explanation: Indian standards heavy weight beam is the heaviest I section beam.
