NEW QUESTION # 40
When Type X gypsum board is used as noncombustible protection over mass timber on the building ' s exterior walls, which of the following fasteners are permitted?
Answer: C
Explanation:
Option A reproduces one of the two permitted exterior gypsum-board fastening methods in 2021 IBC Section
722.7.2.2. Type X gypsum board used as noncombustible protection on the exterior side of mass timber walls may be attached using galvanized nails of minimum 12 gage with a 7/16-inch head and sufficient length to penetrate the mass timber at least 1 inch .
The code also permits ASTM C1002 Type S, W, or G screws, but those screws must likewise penetrate the mass timber a minimum of 1 inch . Options C and D are therefore incorrect because they specify only 3/4- inch and 7/8-inch penetration, respectively. Option B is incorrect because it substitutes 16-gage nails for the minimum 12-gage requirement.
Section 722.7.2.2 additionally requires exterior Type X gypsum-board layers to be fastened 12 inches on center each way and 6 inches on center at joints or ends. Panel-edge fasteners must be located at least 1 inch and not more than 2 inches from the edge.
These fastening details are part of the conditions necessary to claim the protection contribution in Table
722.7.1(2).

NEW QUESTION # 41
Refer to the exhibit by clicking on the EXHIBIT button above.
In the detail shown and according to AWC Technical Report 10, what is the time assigned in minutes to 5/8 in. Type X gypsum board for connection fire protection thermal separation requirements?
Answer: A
Explanation:
For the illustrated two-layer protection system, the 5/8-inch Type X gypsum-board layer directly adjacent to the connection is assigned 20 minutes, while the second layer is assigned 40 minutes. Therefore, option C is correct.
The standard assigned protection time for one layer of 5/8-inch Type X gypsum board is 40 minutes.
However, the thermal-separation methodology applies a 0.50 reduction factor to the final or base Type X layer located directly against the protected connection. That layer therefore contributes 20 minutes. The outer layer retains its full 40-minute assigned value, producing a combined assigned protection time of 60 minutes for the two-layer configuration.
The layers are not interchangeable for calculation purposes because the reduced contribution applies specifically to the layer adjacent to the protected connection. Options A and B incorrectly assign the same value to both layers, while option D reverses the required allocation.
During inspection, the special inspector should verify layer sequencing, board thickness and type, fastening, joint staggering, edge support, protection at corners, and continuity around the connection. Missing or incorrectly sequenced layers can invalidate the calculated thermal-separation time.

NEW QUESTION # 42
Which of the following is true regarding Type IV-B unprotected portions of mass timber ceilings and walls?
Answer: A
Explanation:
Type IV-B construction is fundamentally protected mass timber construction, but the 2021 IBC permits specifically limited areas of interior mass timber to remain exposed. Section 602.4.2.2.2 establishes two independent exposure limits. Unprotected portions of mass timber ceilings, including attached beams, are limited to 20 percent of the floor area of the dwelling unit or fire area. Unprotected portions of mass timber walls, including attached columns, are limited to 40 percent of that floor area . Accordingly, option C correctly states the permitted percentages.
These percentages do not operate in isolation. Exposed areas must also comply with Section 602.4.2.2.4, which establishes separation requirements between unprotected mass timber surfaces. Where both walls and ceilings are exposed within the same dwelling unit or fire area, Section 602.4.2.2.3 requires use of the mixed- unprotected-area equation rather than independently maximizing both percentages.
Option A describes neither Type IV-B nor its controlled-exposure concept. Option B incorrectly characterizes Type IV-B as requiring complete encapsulation. Option D reverses the ceiling and wall percentages.
References/Topics: 2021 IBC Sections 602.4.2.2.2, 602.4.2.2.3 and 602.4.2.2.4; Type IV-B permitted exposed mass timber.
NEW QUESTION # 43
In Type IV-C construction, a connection between two members of the primary structural frame supporting a floor is required to be protected to achieve a minimum fire-resistance rating of:
Answer: B
Explanation:
The required minimum rating is two hours. Under 2021 IBC Table 601, the primary structural frame in Type IV-C construction must provide a two-hour fire-resistance rating. A structural connection joining members of that frame cannot be permitted to fail before the members it connects; consequently, the connection must remain functional for the same required period.
The protection requirement applies to the complete connection assembly. This includes steel plates, hangers, bolts, screws, dowels, fasteners, welds, bearing regions, and portions of the connected timber that form part of the connection. Compliance can be achieved through tested construction, calculated wood cover, Type X gypsum protection, another approved noncombustible system, or a combination documented by the registered design professional.
Option A is insufficient because it would leave a one-hour weakness in a two-hour structural load path.
Option B similarly falls short of the required Table 601 rating. Option D is the Type IV-A primary-frame rating and is not required for the stated Type IV-C condition.
The special inspector must verify protective-cover dimensions and installation before connection hardware becomes concealed, including any project-specific inspection required for calculated wood-cover protection.
References/Topics: 2021 IBC Table 601 and Section 2304.10.1; AWC Fire Design Specification, protection of structural connections.
NEW QUESTION # 44
Buildings of Types IV-A, IV-B, and IV-C construction designed to be greater than six stories above grade plane shall meet which of the following requirements for fire safety practices during construction?
Answer: B
Explanation:
The 2021 IFC specifically requires standpipes to be provided in accordance with Section 3313 for Type IV-A, IV-B, and IV-C buildings designed to exceed six stories above grade plane. Therefore, option A is correct.
The code also requires a water supply for fire department operations, but it must be approved by the fire code official and fire chief; it is not described as a mandatory "portable water supply." This makes option B inaccurate. Where noncombustible protection is required, at least one layer-not two layers-must be installed on applicable building elements more than four levels below active mass timber construction before additional levels are erected. Option D therefore overstates the number of layers.
Required exterior wall coverings must similarly be installed more than four levels below active mass timber construction. Option C incorrectly substitutes two levels for the prescribed four-level threshold.
These provisions limit the amount of unprotected combustible construction exposed at one time and provide the fire department with usable suppression infrastructure as erection progresses. Inspection coordination should verify standpipe extension, hose-connection accessibility, water availability, the progression of passive protection, and exterior-wall covering installation.
