1. Which type of bridge is best suited for long spans over deep
valleys?
A. Beam bridge
B. Suspension bridge
C. Arch bridge
D. Truss bridge
Rationale: Suspension bridges are ideal for long spans because
their cables efficiently distribute loads over great distances.
2. What is the primary material used in reinforced concrete bridge
decks?
A. Wood
B. Concrete with steel reinforcement
C. Aluminum
D. Stone
Rationale: Reinforced concrete combines concrete’s compressive
strength with steel’s tensile strength, making it ideal for decks.
3. What is the main purpose of expansion joints in bridges?
A. Enhance aesthetics
B. Support pedestrian traffic
C. Accommodate thermal expansion and contraction
D. Reduce construction cost
Rationale: Expansion joints allow bridges to expand and contract
with temperature changes without causing structural damage.
,4. In bridge construction, what is a pier?
A. The main cable of a suspension bridge
B. A vertical support between abutments
C. The roadway surface
D. A type of foundation only used in beam bridges
Rationale: Piers are vertical structures that support the bridge
deck between abutments.
5. What is the main advantage of a cable-stayed bridge over a
suspension bridge?
A. Cheaper materials
B. Easier to construct over water
C. Requires less cable and can handle medium spans efficiently
D. Can only be built on short spans
Rationale: Cable-stayed bridges use fewer cables than suspension
bridges and are cost-effective for medium spans.
6. Which method is commonly used for constructing concrete bridge
decks?
A. Cantilever method
B. Cast-in-place and precast segmental construction
C. Suspension method
D. Cable spinning
Rationale: Cast-in-place and precast segmental methods are
standard techniques for concrete deck construction.
7. What is the main function of bearings in a bridge?
A. Anchor the bridge permanently
B. Reduce visual impact
C. Transmit loads from the superstructure to the substructure
while allowing movement
D. Prevent water seepage
Rationale: Bearings accommodate movements due to thermal
expansion and traffic loads while transferring loads safely.
8. Which soil condition is least favorable for bridge foundation
construction?
A. Bedrock
B. Dense sand
, C. Soft clay or loose silt
D. Gravel
Rationale: Soft clay and loose silt have low bearing capacity and
can lead to settlement issues.
9. What is a common type of foundation for large bridge piers?
A. Strip foundation
B. Pad foundation
C. Pile foundation
D. Raft foundation
Rationale: Pile foundations transfer loads to deeper, more stable
soil layers, which is necessary for large bridge piers.
10. Which of the following bridges uses the principle of
compression primarily?
A. Suspension bridge
B. Cable-stayed bridge
C. Arch bridge
D. Cantilever bridge
Rationale: Arch bridges rely on the compressive strength of
materials, transferring loads along the curve to abutments.
11. The term “cantilever” in bridge construction refers to:
A. A suspended pedestrian bridge
B. A temporary scaffolding method
C. A projecting structure supported at only one end
D. A type of cable
Rationale: Cantilever bridges extend horizontally and are
supported only at one end, allowing spans without central support.
12. Which inspection method is commonly used for bridge steel
members?
A. Core sampling
B. Ground-penetrating radar
C. Ultrasonic and magnetic particle inspection
D. Thermography only
Rationale: Ultrasonic and magnetic particle tests detect internal
and surface defects in steel structures.
