1. Which Florida Building Code classification is generally applicable to a building
containing a combination of different occupancy uses when the uses do not
qualify as accessory occupancies?
A. Incidental use area
B. Accessory occupancy
C. Mixed occupancy
D. Utility occupancy
Answer: C. Mixed occupancy
Mixed occupancy provisions address buildings containing more than one
occupancy classification and determine how the applicable requirements are
coordinated.
2. Under the Florida Building Code, which factor is most directly used to
determine the required fire-resistance rating of a structural element?
A. Building color
B. Property value
C. Construction type and applicable code requirements
D. Contractor's license category
Answer: C. Construction type and applicable code requirements
Fire-resistance requirements depend on the construction type, occupancy, building
characteristics, and applicable code provisions.
3. A contractor discovers that the approved construction documents conflict
with an applicable mandatory provision of the Florida Building Code. What
should the contractor do?
,A. Follow the drawings because they were approved
B. Follow the owner's verbal instructions
C. Continue construction and correct it after inspection
D. Obtain clarification and ensure the work complies with the applicable code
Answer: D. Obtain clarification and ensure the work complies with the
applicable code
Approval of documents does not authorize construction that violates mandatory
code requirements.
4. Which component primarily transfers loads from a building's structural frame
to the supporting soil?
A. Roof sheathing
B. Ceiling joist
C. Foundation
D. Interior partition
Answer: C. Foundation
The foundation transfers structural loads to the supporting soil or rock.
5. A footing is being designed for a wall carrying a uniform load. Increasing the
footing width primarily reduces:
A. Roof load
B. Wind pressure
C. Bearing pressure on the soil
D. Dead load of the wall
Answer: C. Bearing pressure on the soil
Increasing bearing area distributes the load over a larger soil area and therefore
reduces average soil pressure.
6. Which soil condition generally presents the greatest concern for differential
settlement?
,A. Uniformly compacted granular soil
B. Competent rock
C. Variable soil conditions beneath the structure
D. Properly compacted engineered fill
Answer: C. Variable soil conditions beneath the structure
Different soil characteristics can produce unequal settlement beneath different
portions of a building.
7. What is the principal purpose of reinforcing steel in a reinforced concrete
beam?
A. Increase concrete color uniformity
B. Eliminate all dead loads
C. Provide tensile resistance where concrete is weak in tension
D. Prevent concrete from becoming alkaline
Answer: C. Provide tensile resistance where concrete is weak in tension
Concrete performs well in compression but has relatively limited tensile capacity;
reinforcing steel provides tensile strength.
8. When placing concrete, excessive addition of water at the job site can
primarily result in:
A. Increased compressive strength
B. Reduced shrinkage
C. Reduced strength and increased shrinkage potential
D. Elimination of segregation
Answer: C. Reduced strength and increased shrinkage potential
Excess water increases the water-cement ratio and can adversely affect strength,
durability, and shrinkage.
9. What is the primary purpose of control joints in concrete slabs?
A. Increase live loads
B. Prevent all movement
, C. Provide a planned location for cracking caused by shrinkage or movement
D. Increase reinforcement strength
Answer: C. Provide a planned location for cracking caused by shrinkage or
movement
Control joints guide cracking to predetermined locations rather than allowing
random cracking.
10. Which condition most directly increases the likelihood of wood decay in a
building?
A. Low humidity and adequate ventilation
B. Properly protected lumber
C. Persistent moisture exposure
D. Properly installed flashing
Answer: C. Persistent moisture exposure
Wood decay fungi require moisture and favorable environmental conditions to
grow.
11. What is the primary function of flashing at a roof-to-wall intersection?
A. Increase roof dead load
B. Provide structural framing
C. Direct water away from vulnerable joints and into the drainage system
D. Replace roof covering
Answer: C. Direct water away from vulnerable joints and into the drainage
system
Proper flashing prevents water intrusion at changes in plane and other vulnerable
locations.
12. A roof has a rise of 6 feet for every 12 feet of horizontal run. What is its
slope?
A. 2:1
B. 1:3
