NEW QUESTION # 34
Proprietary nails can be used by referencing which ICC-ES Evaluation Report?
Answer: D
Explanation:
ICC-ES ESR-1539 is the applicable evaluation report, making option C correct. ESR-1539 addresses nails and staples manufactured by participating companies and evaluates their use in engineered and nonengineered structural connections.
An ICC-ES Evaluation Report provides evidence that a proprietary product or system complies with specified building-code requirements where the product does not rely solely on the generic prescriptive provisions of the IBC. For proprietary nails, the report provides the technical basis needed to establish characteristics such as dimensions, materials, recognized structural applications, allowable design values, installation limitations, and conditions of use.
The current ICC-ES document is published as ESR-1539P, reflecting subsequent administrative updates to the report, but the identifying evaluation-report number remains 1539 , matching option C and the examination question.
For special inspection, merely recognizing the ESR number is not enough. The inspector should verify that the installed proprietary fastener is actually included in the report, that its diameter and length correspond to the approved construction documents, and that installation spacing, penetration, orientation, substrate, and other report conditions are satisfied.
References/Topics: ICC-ES ESR-1539, structural nails and staples; proprietary fastener evaluation and installation requirements. ICC-ES states that the nails and staples covered by ESR-1539 are used in engineered and prescriptive structural connections.
NEW QUESTION # 35
Periodic special inspection of sealants or adhesives as specified by the International Building Code Section
703.7 shall be conducted at which of the following locations?
Answer: C
Explanation:
IBC Section 703.7 requires sealant or adhesive to resist air passage at the abutting edges and intersections of mass timber building elements where those elements are required to be fire-resistance rated. Section 1705.20 then requires periodic special inspection where those prescribed sealants or adhesives are installed. Option C repeats that first required location accurately.
Option D is defective because the code requires sealing at an intersection between mass timber and another material only where both intersecting building elements are required to be fire-resistance rated. The phrase
"one or the other" materially weakens the condition. Option A is also too broad. A code-defined joint is not automatically subject to Section 703.7; fire-resistant joint systems are separately regulated by Section 715 and, where applicable, Section 1705.18.
Option B describes the exception in reverse. Sealant or adhesive need not be added under Section 703.7 where it is not a required component of the tested fire-resistance-rated assembly. When it is part of the listed or tested assembly, it must be installed accordingly, but that statement does not identify the primary location requested.
References/Topics: 2021 IBC Sections 703.7 and 1705.20; sealing of adjacent rated mass timber elements; periodic inspection.
NEW QUESTION # 36
Refer to the exhibit by clicking on the EXHIBIT button above.
In the detail shown, which fasteners require fire protection according to AWC Technical Report 10?
Answer: A
Explanation:
The 1/2-inch lag screws attaching the structural steel ledger require fire protection, making option D correct. These fasteners are structural components of the ledger-to-CLT connection and therefore form part of the connection whose fire performance must be maintained for the required duration.
AWC Technical Report 10 states that wood structural connections-including their connectors, fasteners, and participating members-must be protected from fire exposure for the required fire-resistance time
. Protection may be provided by wood cover, fire-rated gypsum board, other approved materials, or a combination.
TR10 distinguishes structural connection fasteners from small fasteners used merely to hold sacrificial protection in place. The report specifically explains that fasteners attaching protective wood strips need not themselves be protected, provided they are sufficiently long to keep the protection in position throughout the required exposure.
In the illustrated ledger connection, the 1/2-inch lag screws transfer structural load between the steel ledger and CLT wall. Their thermal protection is therefore integral to maintaining connection capacity.
References/Topics: AWC Technical Report No. 10 Sections 4.5 and connection examples; thermal protection of structural connectors and fasteners.
NEW QUESTION # 37
Refer to the exhibit by clicking on the EXHIBIT button above.
In the detail shown, the 2x2 block is intended for what purpose according to AWC Technical Report 10?
Answer: B
Explanation:
The 2 ร 2 block is intended to protect the abutting wood edges from the effects of char contraction. Therefore, option D is correct.
During fire exposure, wood chars and the char layer can shrink or contract. At an interface between two abutting timber components, that contraction can create a gap that allows heat and flames to penetrate deeper than predicted for a continuous exposed surface. AWC connection-fire-design methodology therefore requires additional protection at susceptible joints and interfaces. The block shields the abutting edges and maintains the sacrificial wood-cover path around the protected connection.
Its primary function is not decorative, nor is it simply an air-sealing component. Although limiting airflow can be a secondary consequence of closing the interface, the design purpose addressed by the technical guidance is control of premature fire penetration caused by char contraction. The block also should not be interpreted independently as a generic one-hour protective membrane for the steel ledger; the connection's total rating depends on the complete approved protection assembly.
The inspector should confirm the block's dimensions, species or product designation, fastening, continuity, and tight installation before the connection is concealed.

NEW QUESTION # 38
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 fire-resistance rating is two hours , making option C correct. Table 601 assigns a two- hour fire-resistance rating to the primary structural frame in Type IV-C construction. The structural connection between members of that rated frame cannot become a premature failure point in the load path.
IBC Section 2304.10.1 specifically addresses structural connections in Types IV-A, IV-B, and IV-C mass timber construction. Connection protection must provide the fire-resistance performance required for the connected building element. This can be accomplished through protected connection configurations, approved fire testing, or engineering analysis satisfying the applicable code criteria.
The connection includes more than the visible steel plate or bolt. Fasteners, connectors, concealed steel, bearing zones, and portions of the timber participating structurally in the connection must collectively maintain the required performance. A one-hour or 1ยฝ-hour connection would undermine a structural frame required to remain functional for two hours. Three hours is the primary-frame rating associated with Type IV- A, not the Type IV-C condition specified here.
The inspector should verify protection thickness, wood cover, gypsum layers, hardware embedment, edge conditions, and approved connection geometry before concealment.
