QUESTION 1
Which system is primarily considered a support system in building construction?
A. Roofing membrane system
B. Structural framing system
C. Electrical distribution system
D. Interior paint system
B. Structural framing system
Structural framing systems provide the primary load-bearing support for
buildings, transferring loads safely to the foundation. Unlike finishes or utility
systems, framing directly supports structural integrity, making it a core support
system in construction engineering.
QUESTION 2
The main purpose of a foundation system is to:
A. Improve building aesthetics
B. Transfer loads to the ground safely
C. Provide interior insulation
D. Support electrical wiring
,B. Transfer loads to the ground safely
Foundation systems distribute structural loads from the building into the soil,
preventing settlement or collapse. Their primary engineering role is load transfer
and stability rather than finishing or utility functions.
QUESTION 3
Which soil type generally provides the best load-bearing capacity?
A. Peat
B. Clay
C. Dense gravel
D. Silt
C. Dense gravel
Dense gravel has high friction and low compressibility, making it ideal for
supporting heavy structural loads. It provides excellent drainage and stability
compared to clay or silt, which are more prone to shifting.
QUESTION 4
What is the primary function of a retaining wall?
A. Increase roof strength
B. Prevent soil movement
C. Support electrical lines
D. Improve plumbing flow
B. Prevent soil movement
Retaining walls resist lateral earth pressure, stabilizing soil in sloped or
excavated areas. They prevent erosion and collapse, making them critical in site
stabilization systems.
,QUESTION 5
Which component is commonly used for lateral bracing in structures?
A. Beam
B. Column
C. Diagonal brace
D. Slab
C. Diagonal brace
Diagonal bracing resists lateral forces such as wind or seismic loads. It stabilizes
structures by transferring lateral forces to the foundation system efficiently.
QUESTION 6
What is the primary purpose of shoring during excavation?
A. Decorate excavation sites
B. Prevent soil collapse
C. Improve drainage
D. Increase soil compaction
B. Prevent soil collapse
Shoring supports excavation walls to prevent cave-ins, protecting workers and
maintaining soil stability during construction operations.
QUESTION 7
Which material is most commonly used for temporary shoring?
A. Aluminum
B. Steel
C. Glass
D. Ceramic
B. Steel
, Steel is widely used for shoring due to its high strength, durability, and ability to
withstand heavy lateral loads in temporary structural support systems.
QUESTION 8
What is underpinning used for?
A. Painting structures
B. Strengthening existing foundations
C. Installing plumbing
D. Decorating interiors
B. Strengthening existing foundations
Underpinning is used to stabilize or deepen existing foundations when structural
loads increase or soil conditions change, ensuring continued structural integrity.
QUESTION 9
Which factor most affects soil bearing capacity?
A. Soil color
B. Moisture content
C. Building paint
D. Wind speed
B. Moisture content
Moisture content significantly impacts soil strength; excessive water reduces
cohesion and bearing capacity, increasing settlement risk.
QUESTION 10
A spread footing is designed to:
A. Concentrate loads into one point
B. Distribute loads over a wide area
