1. What is the primary objective of disaster risk engineering in
infrastructure systems?
A) Maximizing construction speed
B) Reducing aesthetic design constraints
C) Minimizing loss of life, property damage, and service disruption
during hazards
D) Increasing material usage in structures
Rationale: Disaster risk engineering focuses on reducing vulnerability
and exposure of systems to hazards to protect lives, assets, and
continuity of essential services.
2. Which of the following best describes “hazard” in risk assessment
terminology?
, A) The economic cost of damage
B) A potentially damaging physical event or phenomenon
C) The probability of human error
D) The resilience capacity of a structure
Rationale: A hazard is any natural or human-induced event capable
of causing harm, such as earthquakes, floods, or storms.
3. In risk analysis, “vulnerability” refers to:
A) The frequency of hazard occurrence
B) The magnitude of seismic waves
C) The susceptibility of a system or structure to damage when
exposed to a hazard
D) The geographic location of a hazard
Rationale: Vulnerability measures how severely a system is affected
when exposed to a hazard event.
4. Which equation best represents basic disaster risk formulation?
A) Risk = Hazard + Exposure
B) Risk = Vulnerability − Capacity
C) Risk = Probability × Resilience
D) Risk = Hazard × Exposure × Vulnerability
Rationale: Risk is commonly modeled as the product of hazard,
exposure, and vulnerability factors.
5. Which structural system is most resistant to lateral seismic forces?
A) Masonry load-bearing walls
, B) Timber frame without bracing
C) Flat slab systems
D) Base-isolated structural systems
Rationale: Base isolation reduces seismic energy transfer to
structures, improving earthquake resistance.
6. The return period of a flood refers to:
A) Time taken for water to drain
B) Duration of a flood event
C) Average interval between flood events of a given magnitude
D) Time required for flood recovery
Rationale: Return period is a statistical measure of likelihood of
recurrence of extreme events.
7. Which soil type is most susceptible to liquefaction during
earthquakes?
A) Clay
B) Gravel
C) Rock
D) Loose saturated sandy soil
Rationale: Loose saturated sands lose strength under seismic
shaking, leading to liquefaction.
8. The primary purpose of building codes in disaster engineering is to:
A) Increase construction cost
B) Limit architectural innovation
, C) Ensure minimum safety and performance standards under hazards
D) Standardize building colors
Rationale: Building codes establish safety requirements to reduce
structural failure risks.
9. What is the main function of a retaining wall in geotechnical
engineering?
A) Increase soil permeability
B) Reduce rainfall intensity
C) Prevent soil movement and slope failure
D) Improve air circulation
Rationale: Retaining walls stabilize soil and prevent landslides or
erosion.
10. Which hazard is most associated with El Niño events?
A) Earthquakes
B) Volcanic eruptions
C) Flooding and drought variability
D) Tornadoes exclusively
Rationale: El Niño alters atmospheric circulation, increasing flood
and drought risks.
11. Structural redundancy in engineering design refers to:
A) Reducing material use
B) Increasing aesthetic features
C) Providing multiple load paths to prevent collapse
