1. Which condition is most important when determining the
appropriate design of a support system?
A. Paint color of the structure
B. Magnitude and direction of applied loads
C. Age of nearby landscaping
D. Type of interior flooring
Rationale: Support systems must be designed to resist the loads
imposed on them safely. The magnitude, direction, duration, and
location of loads directly affect member sizes, connections,
foundations, and overall stability.
2. What is the primary purpose of a temporary support system?
,A. Improve architectural appearance
B. Reduce material costs
C. Maintain structural stability while permanent work is incomplete
D. Eliminate the need for inspections
Rationale: Temporary supports transfer or resist loads while
construction, repair, demolition, or alteration work is underway. They
help prevent excessive movement or collapse until the permanent
structural system can safely carry the loads.
3. Which type of load is caused by the weight of permanent
structural and nonstructural components?
A. Live load
B. Wind load
C. Impact load
D. Dead load
Rationale: Dead loads are permanent or relatively fixed loads,
including structural members, roofing, walls, finishes, and
permanently attached equipment. They differ from live loads, which
can change during the life of the structure.
4. What is the primary function of a brace in a support system?
,A. Provide decorative trim
B. Resist lateral movement and improve stability
C. Reduce concrete curing time
D. Increase paint adhesion
Rationale: Bracing provides resistance against lateral displacement,
buckling, and instability. Properly positioned braces can significantly
increase the ability of a temporary or permanent support system to
remain stable under applied loads.
5. Before installing temporary shoring, what should be verified first?
A. The weather forecast only
B. The color of the shoring members
C. The existing structure, anticipated loads, and supporting ground or
structure
D. The number of workers available
Rationale: Shoring transfers loads into other structural elements or
into the ground. Those supporting elements must be capable of
carrying the transferred loads without excessive settlement,
deformation, or failure.
6. What is a primary concern when placing a concentrated load on
an existing slab?
, A. Surface color
B. Electrical voltage
C. Local overstress or punching failure
D. Window placement
Rationale: A concentrated support reaction can create high localized
stresses in a slab. Depending on the slab type and reinforcement,
punching shear, bending, cracking, or local crushing can occur.
7. What does the term “load path” describe?
A. The route workers use to enter a jobsite
B. The location of construction equipment
C. The continuous transfer of loads through structural components to
the foundation or ground
D. The direction of material deliveries
Rationale: A safe structural system requires a continuous load path.
Loads must be transferred from floors, roofs, walls, beams, and
columns through connections and foundations into the supporting
soil.
8. Why are connections particularly important in a support system?
A. They determine the building's paint requirements
B. They transfer forces between structural members
