1. Which is the most commonly used method to measure concrete workability?
A. Flow table test
B. Compaction factor test
C. Slump test
D. Vee-Bee test
Answer: C) Slump test
Rationale: The slump test is widely used to measure the workability of concrete by
assessing its consistency and fluidity.
2. What is the main function of a shear wall in a building?
A. To provide support against vertical loads
B. To resist horizontal loads due to wind and earthquakes
C. To enhance the aesthetic appearance of the structure
D. To prevent the building from tilting
Answer: B) To resist horizontal loads due to wind and earthquakes
Rationale: Shear walls are primarily used to resist lateral forces caused by wind and
seismic activity.
,3. Which of the following is not a property of cement?
A. Compressive strength
B. Flexural strength
C. Durability
D. Ductility
Answer: D) Ductility
Rationale: Cement is a brittle material and lacks ductility, which is the ability to
deform plastically before breaking.
4. What is the main purpose of a column in a structure?
A. To resist bending
B. To support the superstructure
C. To carry wind loads
D. To resist shear stress
Answer: B) To support the superstructure
Rationale: The primary function of a column is to support the superstructure (the load-
bearing part of the building) and transfer the loads to the foundation.
, 5. Which of the following is the correct formula for calculating the deflection of a
cantilever beam under a point load at the free end?
A. δ=PL33EI\delta = \frac{PL^3}{3EI}δ=3EIPL3
B. δ=PL34EI\delta = \frac{PL^3}{4EI}δ=4EIPL3
C. δ=PL43EI\delta = \frac{PL^4}{3EI}δ=3EIPL4
D. δ=PL2EI\delta = \frac{PL^2}{EI}δ=EIPL2
Answer: A) δ=PL33EI\delta = \frac{PL^3}{3EI}δ=3EIPL3
Rationale: The deflection at the free end of a cantilever beam under a point load is
given by δ=PL33EI\delta = \frac{PL^3}{3EI}δ=3EIPL3, where PPP is the load, LLL
is the length, EEE is the modulus of elasticity, and III is the moment of inertia of the
beam.
6. If the length of a column is doubled, the buckling load will be:
A. Doubled
B. Halved
C. Four times the original load
D. One-fourth the original load
Answer: D) One-fourth the original load
A. Flow table test
B. Compaction factor test
C. Slump test
D. Vee-Bee test
Answer: C) Slump test
Rationale: The slump test is widely used to measure the workability of concrete by
assessing its consistency and fluidity.
