1110 • iv <br /> Mr. Nathan Crawford <br /> Plan Check Number: B1907-025, First Structural Review <br /> August 6, 2019 <br /> c. Continuing with the previous comment, the stringers appear to potentially be supported by <br /> a single board. The support for this board is not clear. <br /> d. The platform appears to partially rely on support from the existing structure. The load path <br /> shall be clarified. <br /> e. The plans do not appear to show all connections between the framing. Proprietary products <br /> shall be identified in the structural notes. The connection model numbers shall be specified. <br /> The components shall be provided with a coating or made from materials that are resistant <br /> to corrosion. <br /> f. Calculations substantiating the design of the framing and connections shall be submitted for <br /> review. The design shall consider the live loads per IBC Table 1607.1 Item 30. <br /> g. Calculations substantiating the design of the stringers shall be submitted for review. The <br /> design shall consider the reduced cross-section. <br /> 14. Sheets 3 through8 shows plans and elevations for the proposed deck and canopy on the east <br /> side of the building. See IBC Section 1603.1. The following comments shall be addressed: <br /> a. The drawings specify"ledgerlocks"and"headlocks"fasteners. These fasteners shall be <br /> clarified. Proprietary products shall be identified in the structural notes. The fastener sizes <br /> shall be specified (e.g., diameter and length, model numbers, etc.). <br /> b. Nailing requirements for the floor and roof sheathing shall be specified. <br /> c. The plans do not appear to show all connections between the framing. Proprietary products <br /> shall be identified in the structural notes. The connection model numbers shall be specified. <br /> The components shall be provided with a coating or made from materials that are resistant <br /> to corrosion. <br /> d. Calculations substantiating the design of the framing and connections shall be submitted for <br /> review. The design shall consider the live loads per IBC Table 1607.1 Item 30. <br /> Lateral System: <br /> 15. Calculations shall be submitted for review substantiating the lateral load path for the east deck <br /> and canopy. The calculations shall evaluate all members and connections in the load path. The <br /> structure shall be evaluated for both wind and seismic loading. Note that the load path is not a <br /> type specified in ASCE 7-10 Table 12.2-1, and shall be established per Section 12.2.1. The roof <br /> canopy is eccentrically-restrained along one side in the longitudinal direction, and shall be <br /> evaluated as a rigid diaphragm per AWC SDPWS-15 Section 4.2.5.2. See IBC Sections 1604.1 <br /> and 1604.1. <br /> 16. Continuing with the previous comment, the custom bracket shown on pages 5 and 6 does not <br /> appear to provide an adequate load path, particularly in the longitudinal direction where loading <br /> is expected to pry the fasteners from the existing building framing. Calculations shall be <br /> submitted for review substantiating the design of the bracket and fasteners. All portions of the <br /> bracket shall be evaluate for induced loading. Based on a review of the framing and expected <br /> loading conditions, the bracket and fasteners will be required to resist simultaneous triaxial <br /> loading (i.e., gravity, lateral, and torsional loads) from the roof canopy. See IBC Sections <br /> 1604.1 and 1604.4. <br /> a3200 <br /> Cedar Street 0 425.257.8810 0 everetteps@everettwa.gov <br /> Everett,WA 98201 425.257.8857 fax everettwa.gov/permits <br /> Page 4 of 5 <br />
