O <br /> Mr. McItvain <br /> CRM Architects&Planners, Inc. <br /> Plan Check Number: B1805-010, Second Review <br /> December 4, 2018 <br /> 32.This comment has not been addressed. The revised drawings do not appear to include a <br /> detail for the truss-to-beam connection. The trusses should be provided with a positive <br /> horizontal connection to the beam. Alternatively, crossties may be provided interconnecting <br /> the truss top chords. The connections shall provide a minimum capacity of 5% of the truss <br /> dead and live load reaction at the support. The connections shall also provide wind uplift <br /> resistance as required. See IBC Sections 1609.1 and 1613.1, and ASCE 7-10 Section 12.1.4. <br /> See Structural Response letter <br /> 33.This comment has not been addressed. The response is not sufficient to clarify how the <br /> comment was addressed. See IBC Sections 1603.1, 1604.1, 1604.4, 1609.1, and 1613.1. <br /> The following comments should be addressed: <br /> a. Horizontal connections to resist out-of-plane loading shall be provided. <br /> b. Calculations substantiating the connections for out-of-plane loading, including but not <br /> limited to wind leeward pressures, shall be submitted for review. The connections shall <br /> also provide a minimum capacity of 5% of the truss dead and live load reaction at the <br /> support per ASCE 7-10 12.1.4. <br /> c. No additional comment. <br /> See Structural Response letter <br /> 34.This comment has not been addressed. The response is not sufficient to clarify how the <br /> comment was addressed. See IBC Sections 1603.1, 1604.1, 1604.4, and 1609.1. The <br /> following comments should be addressed: <br /> a. Details shall be provided for the out-of-plane connection between the walls and roof <br /> diaphragm. <br /> b. The diaphragm shall be provided with subdiaphragms and crossties of sufficient depth to <br /> develop the wall loads into the diaphragm. <br /> c. Calculations substantiating the connections for out-of-plane loading, including but not <br /> limited to wind leeward pressures, shall be submitted for review. <br /> d. No additional comment. <br /> See Structural Response letter <br /> Miscellaneous: <br /> 35.This comment has not been addressed. The response is not sufficient. The roof supports <br /> heavy mechanical equipment per Sheet S-2.1. The equipment is expected to require <br /> supplemental structural framing (e.g., curbs) and anchorage to the roof structure. Details <br /> and calculations for the structural support of the equipment should be submitted for review. <br /> Alternatively, the anchorage and support framing shall be listed in the Deferred Submittals <br /> on Sheet S-1.0. See IBC Sections 1603.1, 1604.1, and 1613.1, and ASCE 7-10 Section 13.6. <br /> See Structural Response letter <br /> 0 <br /> 3200 Cedar Street 425.257.8800 everettpw@everettwa.gov <br /> Everett,WA 98201 CD 425.257.8882 fax • everettwa.gov <br />
