질문 # 48
In mass timber construction of Type IV-C, the fire-resistance ratings of bearing walls are permitted to be reduced by _____ where supporting a roof only.
정답：B
설명：
IBC Table 601, Footnote "a," permits a one-hour reduction in the required fire-resistance rating of the primary structural frame and bearing walls where those elements support a roof only. Option C is therefore correct.
For Type IV-C construction, the normal Table 601 requirement for bearing walls is two hours. Where a bearing wall qualifies as supporting only roof construction, application of the footnote permits that rating to be reduced from two hours to one hour.
The limitation "supporting a roof only" is critical. The reduction cannot be applied simply because a wall is located at the uppermost occupied level. If the wall carries a floor, mezzanine, transfer load, occupied rooftop structure, or another structural element beyond qualifying roof construction, the condition for the reduction is not satisfied.
Options A and B are not reductions prescribed by Table 601. Option D would effectively eliminate the entire normal two-hour Type IV-C bearing-wall rating, which the footnote does not permit.
For inspection purposes, the approved construction documents and structural load path must substantiate use of the reduction. The fire-protection installation should then be checked against the actual reduced rating specifically authorized by the design.

Refer to the exhibit by clicking on the EXHIBIT button above.
In the detail shown, what is the required screw spacing in inches for the CLT to glulam connection?
정답：C
설명：
The connection detail specifies the CLT-to-glulam screws at 24 inches on center , so option D is correct. This is a construction-document interpretation question rather than a universal prescriptive screw-spacing requirement imposed by the IBC.
The approved structural detail controls the required spacing for this particular connection because the registered design professional has established the connection geometry and fastener schedule based on the applicable structural loads, CLT panel configuration, glulam member, fastener properties, and required load transfer. The 24-inch dimension must therefore be maintained in the field unless an approved revision changes the connection design.
IBC Table 1705.5.3 is directly relevant to the special inspector's responsibilities. For screws used in Type IV- A, IV-B, or IV-C mass timber connections, periodic special inspection includes verification of diameter, length, head type, spacing, installation angle, and installation depth . The special inspector is therefore expected to compare actual field installation against precisely this type of approved connection detail.
Substituting 12-, 16-, or 20-inch spacing without design authorization would constitute a deviation from the approved documents, even if the alternate spacing appeared more conservative.

질문 # 50
Based on the definition of cross-laminated timber (CLT), panels are manufactured as follows:
정답：C
설명：
The 2021 IBC definition of cross-laminated timber describes a prefabricated engineered wood product consisting of not less than three layers of solid-sawn lumber or structural composite lumber. The adjacent layers are cross oriented and bonded with structural adhesive to form a solid wood element. Accordingly, option C is correct.
Cross orientation means that the principal grain direction of one layer is arranged approximately perpendicular to that of the adjoining layer. This configuration distinguishes CLT from products in which all laminations run parallel, such as conventional glued-laminated timber. The cross-oriented layup provides two- way panel behavior, dimensional stability, and structural capacity in both principal directions.
Option A is incorrect because CLT must contain at least three layers. Option B describes a mechanically laminated product rather than structural glued CLT; nail-laminated timber uses mechanical fasteners, whereas code-compliant CLT uses structural adhesives and must conform to the applicable manufacturing standard.
Option D eliminates the defining cross-lamination characteristic and would instead describe a parallel- laminated product.
During inspection, the product label and certification documentation should be checked to confirm the panel was manufactured under the required quality-assurance program.

2303.1.4; ANSI/APA PRG 320.
질문 # 51
Where Type X gypsum board serves as noncombustible protection for interior surfaces of wall and ceiling assemblies, all of the following code provisions are correct except:
정답：D
설명：
Option D is the incorrect statement. IBC Section 722.7.2.1 requires the panel edges of the face layer , rather than the base layer, to be taped and finished with joint compound. Fastener heads on the face layer must also be covered with joint compound.
The other three provisions accurately reproduce the code. Each gypsum-board layer must be secured with Type S drywall screws long enough to penetrate the mass timber at least 1 inch when driven flush. Screws for the base layer are installed at 12 inches on center in both directions . Subsequent layers use the same general spacing but are offset from screws in the preceding layer. In addition, the panel edges of each succeeding layer must be offset 18 inches from the panel edges of the previous layer.
These details are not merely workmanship recommendations. They form part of the installation conditions under which the protection contributions in Table 722.7.1(2) can be credited.

질문 # 52
What fire-resistance rating is required for Type IV-C exterior and interior bearing walls?
정답：C
설명：
IBC Table 601 requires both exterior and interior bearing walls in Type IV-C construction to have a minimum two-hour fire-resistance rating. Option B is correct.
For exterior bearing walls, the Table 601 rating is not the only applicable criterion. Section 602.1 also requires exterior walls to satisfy Table 705.5 based on occupancy and fire separation distance. Where Table 705.5 or another provision imposes a more restrictive rating, the higher requirement governs.
The two-hour rating may be achieved through the calculated structural fire resistance of the mass timber, approved noncombustible protection, or an approved combination of the two. Connections, intersections, penetrations, and abutting edges must not create a premature failure path or compromise the rated assembly.
A one-hour reduction can be permitted for bearing walls supporting a roof only under Table 601, Footnote
"a," but that exception does not apply to a wall carrying floors or other qualifying structural loads. The inspector must confirm the actual load path before accepting any reduced protection at the uppermost level.
