,Q1. A contractor is constructing a two-story commercial building with a flat roof in a high-wind zone. The
structural plan calls for roof-to-wall connections using hurricane clips. Which of the following best describes
the primary failure mode that these clips are designed to prevent?
A. Uplift due to negative wind pressure on the roof
B. Lateral sliding of the roof diaphragm relative to the wall
C. Overturning of the wall due to windward pressure
D. Shear failure at the roof-to-wall interface from seismic loads
Correct Answer: A. Uplift due to negative wind pressure on the roof
Rationale: Hurricane clips are specifically designed to resist uplift forces caused by wind suction on the roof.
While they also provide some lateral resistance, their primary purpose is to prevent the roof from being lifted off
the walls during high winds. Lateral sliding (B) is addressed by shear walls and diaphragms; overturning (C) is
mitigated by wall anchorage and foundation design; seismic shear (D) is handled by different connectors.
Why Wrong:
B - Lateral sliding is primarily resisted by diaphragm-to-wall connections and shear walls, not specifically by
hurricane clips.
C - Overturning is a global stability issue addressed by wall-to-foundation connections and building
geometry.
D - Seismic shear is typically resisted by shear walls and moment frames; hurricane clips are not designed for
cyclic seismic loading.

Q2. During a framing inspection on a multi-story wood-frame structure, the inspector observes that the top
plates of interior bearing walls are not spliced at intersections. Which code provision is most directly
violated?
A. IRC R602.3(1) - top plates must be continuous over supports
B. IRC R602.3(2) - splices must be at least 24 inches apart
C. IRC R602.3(3) - top plates must be lapped at corners and intersections
D. IRC R602.3(4) - top plates must be tied with metal straps at splices
Correct Answer: C. IRC R602.3(3) - top plates must be lapped at corners and intersections
Rationale: IRC Section R602.3(3) requires that top plates be lapped at corners and intersections of interior
bearing walls to provide continuity and load transfer. While continuity over supports (A) and splice spacing (B) are
important, the specific violation here is the lack of lapping at the intersection. Metal straps (D) are required for
splices in single top plates, but the code first requires lapping.
Why Wrong:
A - Continuity over supports is required, but the issue is at the intersection, not over a support.
B - Splice spacing is relevant for splices, but the top plates are not spliced at all at the intersection.
D - Metal straps are required for single top plate splices, but the primary requirement is lapping at
intersections.

, Q3. A contractor is pouring a concrete foundation wall in a region with expansive soils. The geotechnical
report recommends a minimum depth of 12 inches of granular fill beneath the footing. What is the primary
purpose of this granular layer?
A. To provide a capillary break to prevent moisture migration into the slab
B. To distribute the load from the footing to a wider area of soil
C. To allow for drainage and reduce hydrostatic pressure against the wall
D. To mitigate the effects of soil volume change on the foundation
Correct Answer: D. To mitigate the effects of soil volume change on the foundation
Rationale: In expansive soils, a granular fill layer acts as a cushion to accommodate soil volume changes
(swelling/shrinkage) and reduce differential movement transmitted to the foundation. While it also aids drainage
(C), the primary purpose in expansive soils is to mitigate the effects of soil volume change. Capillary break (A) is a
secondary benefit; load distribution (B) is the function of the footing itself, not the fill.
Why Wrong:
A - A capillary break is a separate function, typically provided by a vapor barrier under the slab.
B - Load distribution is achieved by the footing width, not the granular fill beneath it.
C - Drainage is important but secondary; the geotechnical recommendation specifically addresses expansive
soil mitigation.

Q4. A commercial building design includes a 30-foot-long steel beam with a simple span. The beam is
laterally braced only at the supports. Which of the following limit states will most likely govern the design of
this beam?
A. Yielding of the compression flange
B. Lateral-torsional buckling
C. Web crippling at the supports
D. Local flange buckling
Correct Answer: B. Lateral-torsional buckling
Rationale: For a simply supported steel beam with no intermediate lateral bracing, lateral-torsional buckling
(LTB) is the governing limit state for flexural strength when the unbraced length exceeds the limiting length for
plastic or inelastic LTB. Yielding (A) only governs if the beam is fully braced; web crippling (C) is a local effect at
concentrated loads; local flange buckling (D) is a different limit state that depends on flange slenderness.
Why Wrong:
A - Yielding governs only when the beam is continuously braced against LTB.
C - Web crippling is a local failure at points of concentrated loads, not a global flexural limit state.
D - Local flange buckling is a plate buckling phenomenon that may occur in slender sections, but LTB is more
critical for unbraced beams.

laterally braced only at the supports. Which of the following limit states will most likely govern the design of
this beam?
A. Yielding of the compression flange
B. Lateral-torsional buckling
C. Web crippling at the supports
D. Local flange buckling
Correct Answer: B. Lateral-torsional buckling
Rationale: For a simply supported steel beam with no intermediate lateral bracing, lateral-torsional buckling
(LTB) is the governing limit state for flexural strength when the unbraced length exceeds the limiting length for
plastic or inelastic LTB. Yielding (A) only governs if the beam is fully braced; web crippling (C) is a local effect at
concentrated loads; local flange buckling (D) is a different limit state that depends on flange slenderness.
Why Wrong:
A - Yielding governs only when the beam is continuously braced against LTB.
C - Web crippling is a local failure at points of concentrated loads, not a global flexural limit state.
D - Local flange buckling is a plate buckling phenomenon that may occur in slender sections, but LTB is more
critical for unbraced beams.
