1. What is the primary purpose of a structural beam in a
building?
A. To resist axial compression only
B. To resist bending and shear forces
C. To support electrical wiring
D. To increase insulation
Rationale: Beams primarily resist bending moments and shear
forces created by loads applied perpendicular to their length.
Correct Answer: B
2. Which material is most commonly used for reinforcing
concrete?
A. Aluminum
B. Steel
C. Copper
D. Plastic
Rationale: Steel reinforcement is used because it has high
tensile strength and bonds well with concrete.
Correct Answer: B
,3. What type of load is caused by the weight of building
materials and permanent fixtures?
A. Live load
B. Dead load
C. Impact load
D. Wind load
Rationale: Dead loads are permanent loads such as the weight
of walls, floors, and roofs.
Correct Answer: B
4. The point where two or more structural members meet is
called a:
A. Span
B. Node
C. Joint
D. Axis
Rationale: A joint (or node) is the connection point in structural
systems like trusses and frames.
Correct Answer: C
5. Which structural member primarily carries compression
loads?
A. Tie rod
B. Beam
,C. Column
D. Cable
Rationale: Columns are vertical members designed mainly to
resist compressive forces.
Correct Answer: C
6. What does the term “factor of safety” refer to?
A. Ratio of applied load to allowable load
B. Ratio of failure load to working load
C. Ratio of weight to volume
D. Ratio of stress to strain
Rationale: The factor of safety is the ratio between the
maximum load a structure can handle and the load expected
during use.
Correct Answer: B
7. Which structural system uses triangular units for stability?
A. Frame system
B. Truss system
C. Shell system
D. Grid system
Rationale: Trusses use triangular arrangements to distribute
loads efficiently and maintain rigidity.
Correct Answer: B
, 8. The measure of deformation in a material due to stress is
called:
A. Stress
B. Strain
C. Deflection
D. Modulus
Rationale: Strain measures the relative change in length caused
by applied stress.
Correct Answer: B
9. What is the unit of stress in the SI system?
A. Pascal
B. Newton
C. Joule
D. Watt
Rationale: Stress is force per unit area and is measured in
Pascals (Pa).
Correct Answer: A
10. Which test is commonly used to determine concrete
compressive strength?
A. Tension test
B. Compression test
