1. During a routine bridge inspection, what is the primary purpose of
performing a hands-on inspection rather than only a visual inspection?
A. To reduce inspection costs
B. To eliminate the need for traffic control
C. To detect defects that may not be visible from a distance, including
cracks, corrosion, and section loss
D. To verify bridge ownership
Rationale: Hands-on inspections allow inspectors to closely examine
structural members and identify deterioration that cannot be reliably
detected through distant visual observation. Such inspections improve the
accuracy of condition assessments.
2. Which type of crack in a reinforced concrete bridge girder is generally
considered most indicative of flexural distress?
A. Horizontal crack near the neutral axis
B. Vertical crack originating from the tension face near midspan
,C. Diagonal crack near the support due to shrinkage
D. Random surface crazing
Rationale: Vertical cracks near midspan commonly result from flexural
tension exceeding the tensile strength of concrete and are important
indicators of bending behavior.
3. The primary function of bridge bearings is to:
A. Increase deck friction
B. Prevent corrosion
C. Transfer loads while accommodating movement and rotation
D. Support utilities
Rationale: Bearings safely transfer vertical and horizontal loads from the
superstructure to the substructure while allowing thermal expansion,
contraction, and rotational movement.
4. Excessive pack rust between built-up steel members primarily causes:
A. Improved structural strength
B. Increased ductility
C. Expansion forces that distort connected members
D. Reduced dead load
Rationale: Rust occupies more volume than steel, creating expansive forces
that separate plates, deform connections, and accelerate deterioration.
5. Which inspection finding requires the most immediate structural
evaluation?
A. Minor paint fading
B. Surface dirt accumulation
C. Hairline shrinkage cracks
D. Fracture of a primary tension member
,Rationale: A fractured primary tension member may significantly reduce
structural capacity and requires immediate engineering assessment.
6. Fatigue cracking in steel bridges most commonly develops due to:
A. Earthquakes
B. Wind alone
C. Repeated cyclic loading from traffic
D. Thermal expansion only
Rationale: Fatigue results from repeated stress cycles, even when
individual stresses remain below the yield strength of steel.
7. Delamination in reinforced concrete bridge decks is commonly caused
by:
A. UV radiation
B. Excessive curing
C. Corrosion-induced expansion of reinforcing steel
D. Wind erosion
Rationale: Corrosion products expand, creating internal pressures that
separate concrete layers and eventually lead to spalling.
8. Which nondestructive testing method is commonly used to detect
internal flaws in steel welds?
A. Schmidt hammer
B. Half-cell potential
C. Ultrasonic testing
D. Slump testing
Rationale: Ultrasonic testing uses high-frequency sound waves to identify
internal discontinuities within welded connections.
9. A bridge classified as fracture critical generally:
, A. Has no steel members
B. Cannot carry heavy trucks
C. Contains nonredundant members whose failure could result in collapse
D. Requires inspection every 10 years
Rationale: Fracture-critical bridges contain members without alternate
load paths, making their integrity especially important.
10. What is the primary purpose of an underwater bridge
inspection?
A. Measure bridge width
B. Assess pavement markings
C. Evaluate submerged foundations and scour conditions
D. Inspect lighting fixtures
Rationale: Underwater inspections assess foundation stability, scour,
marine growth, and deterioration below the waterline.
11. Bridge scour refers to:
A. Surface rust formation
B. Paint deterioration
C. Removal of soil surrounding foundations by flowing water
D. Concrete carbonation
Rationale: Scour removes supporting material around foundations and is
one of the leading causes of bridge failures.
12. Which component primarily resists horizontal forces transmitted
from the superstructure?
A. Expansion joint
B. Wearing surface
C. Substructure including piers and abutments
D. Drainage scupper
