1. The purpose of seismic design in California is to:
A. increase construction speed
B. C. improve safety and reduce damage
C. lower material costs
D. simplify engineering plans
it ensures structures withstand earthquake forces.
2. Seismic forces on a structure are primarily due to:
A. wind loads
B. gravity
C. thermal expansion
D. inertial forces caused by ground motion
earthquake ground motion produces inertia in the structure.
3. The seismic design category (SDC) is based on:
A. soil type only
B. seismic risk, occupancy, and importance
C. building height only
D. roof shape
it determines required seismic detailing based on risk.
,4. Base isolation in buildings is used to:
A. increase lateral stiffness
B. reduce construction time
C. decouple the structure from ground motion
D. eliminate gravity loads
allows movement between structure and ground, reducing forces.
5. The California Building Code (CBC) adopts which seismic design
standard?
A. ASCE 7
B. ASCE 7
C. AISC
D. ACI 318
ASCE 7 provides minimum load provisions including seismic.
6. The primary seismic design parameter in ASCE 7 is:
A. wind speed
B. live load
C. response spectrum acceleration values
D. soil moisture
response spectrum defines expected seismic acceleration.
7. Site Class in seismic design relates to:
A. occupancy category
B. soil profile and stiffness
C. roof type
D. foundation type
soil affects seismic wave amplification.
8. A short-period spectral acceleration (SDS) is used to:
A. calculate wind loads
, B. measure temperature effects
C. design lateral forces for short natural periods
D. determine snow loads
used in computing design base shear.
9. Importance Factor (I) increases seismic forces for:
A. residential buildings
B. essential facilities
C. low-risk structures
D. parking garages
essential facilities must withstand stronger events.
10. Seismic Response Modification Coefficient (R) accounts for:
A. aesthetics
B. ductility and energy dissipation
C. fire resistance
D. cost savings
high ductility systems have higher R values.
11. The base shear (V) in seismic design depends on:
A. dead load only
B. seismic coefficient and weight
C. wind load
D. roof pitch
base shear = seismic coefficient × weight.
12. Ductility in seismic design refers to:
A. stiffness
B. capacity to deform without failing
C. brittleness
