1. A framing contractor is reviewing plans for a multistory wood-
framed building. Before beginning construction, which action is
most important for ensuring that the framing work conforms to the
approved structural design?
A. Selecting lumber based only on appearance and availability
B. Installing exterior sheathing before reviewing structural details
C. Reviewing the approved plans, specifications, structural notes, and
applicable code requirements
D. Allowing field workers to determine structural member sizes as
construction progresses
Rationale: Reviewing the approved construction documents and
applicable code requirements ensures that member sizes, connections,
spans, loads, and construction methods conform to the intended
structural design.
2. What is the primary structural purpose of a properly installed sill
plate in wood-frame construction?
,A. To provide a finished surface for interior flooring
B. To support roof sheathing directly
C. To eliminate the need for anchor bolts
D. To provide a connection and bearing surface between the foundation
and the framed wall system
Rationale: The sill plate forms the interface between the foundation and
wall framing and is typically anchored to resist movement while
distributing loads into the foundation.
3. Pressure-treated lumber is commonly required where wood framing
is in direct contact with concrete or masonry primarily because:
A. Concrete always increases the structural strength of untreated lumber
B. Untreated lumber cannot be cut accurately after installation
C. Concrete and masonry can retain moisture that contributes to wood
decay
D. Pressure-treated lumber is always less expensive than ordinary framing
lumber
Rationale: Concrete and masonry can transfer or retain moisture,
creating conditions favorable for fungal decay; preservative-treated
wood provides improved resistance in these locations.
4. When laying out wall studs at 16 inches on center, the primary
purpose of consistent spacing is to:
A. Eliminate the need for wall sheathing
B. Reduce the number of headers over openings
,C. Provide predictable load distribution and alignment with standard
sheathing and finish materials
D. Allow every stud to span independently between floors
Rationale: Standardized stud spacing improves load distribution and
allows panel products such as sheathing and gypsum board to be
installed efficiently with supported edges.
5. Which framing component is generally installed horizontally at the
top of a wall to tie studs together and support framing above?
A. Sole plate
B. Rim joist
C. Header jack
D. Top plate
Rationale: The top plate ties the upper ends of wall studs together and
provides a bearing and connection surface for floor or roof framing
above.
6. In a conventional wood-framed wall opening, what is the principal
purpose of a header?
A. To provide a nailing surface for baseboard
B. To support drywall at the bottom of the opening
C. To transfer loads around an opening to supporting framing members
at each side
D. To prevent insulation from entering the wall cavity
, Rationale: A header spans over an opening and transfers loads from
framing above to supporting studs located beside the opening.
7. Which member directly supports the end of a header in a typical
wood-framed opening?
A. Cripple stud
B. Common stud
C. Blocking member
D. Jack stud
Rationale: Jack studs, also called trimmer studs, provide direct bearing
support beneath headers and transfer header loads toward the bottom
plate and supporting structure.
8. A king stud in conventional wall framing is generally identified as
the stud that:
A. Is cut shorter to fit beneath a window sill
B. Supports only interior trim
C. Runs horizontally between adjacent studs
D. Extends continuously from the bottom plate to the top plate
alongside an opening
Rationale: A king stud is normally full height and works with the jack
stud to frame and reinforce the sides of openings.
9. What is the principal function of cripple studs located above a
header?
