Mr. Ermias Kau eMD Design Practice Plan Check Number: B2203-001, First Building Review May 3, 2022 4. The number and spacing of the deck stair stringers in the Framing Plan on Sheet S2.1 is not dear. The joist spacing and spans should not exceed Table R302.3.1(2) considering a minimum 40 psf live load. Joists should be based on the net depth after notching for stairs. Additional sistered framing may be required for strength and is recommended to control deflections; fasteners should be specified. See Sections R106.1.1 and R301.1. 5. Upper Plan 2/A2.2 includes a new window opening in the south exterior wall. A header, and king and jamb studs, should be specified. See Sections R306.1.1 and R602.7 6. The Roof Framing Plan on Sheet S2.2 includes discontinuous shear walls supported by a beam at the new addition. Multiple shear walls appear to be discontinuous and transfer holdown loads through supporting beams. The beams are required to be designed for seismic loads including overstrength per ASCE 7-16 Section 12.3.3.3. The design loads should include vertical load effects per Section 12.4.2.2. Calculations substantiating the design should be submitted for review. See IBC Sections 1604.1 and 1604.4. 7. Structural calculations for the shear wall holdown anchorage to the concrete foundations should be submitted for review. The earthquake component of the uplift forces exceeds 20% of the total uplift (i.e., the earthquake force is 100% of uplift force). The earthquake component should be increased per the provisions of ACI 318-14 Section 17.2.3.4.3. The design load should include the vertical seismic load effect per Section 12.4.2.2. See IBC Sections 1604.10, 1613.1, and 1901.2. 8. The Upper Level addition has a Type 2 Horizontal Irregularity per ASCE 7-16 Table 12.3-1 on the north side, and a Type 4 Vertical Irregularity per ASCE 7-16 Table 12.3-2 on the north and west sides. The diaphragm chords at the second floor and roof are required to be developed into the main building structure to transfer lateral forces. See IBC Sections 1604.1, 1604.4, 1613.1, and 2306.1. The following comments should be addressed: a. Chords and connections to transfer lateral forces from the addition to the main building should be specified in the framing plans. b. The chords should be developed in the main building diaphragms considering increased loading per Section 12.3.3.4. See also AWC SDPWD-15 Sections 4.1.4 and 4.2.6. 9. Details for the roof overfiaming construction should be provided. The details should specify interconnection of the existing and new diaphragm sheathing. See Section R106.1.1. 10. The connection requirements appear to be missing for the new addition Upper Floor Framing Plan on Sheet S2.1. See Sections R106.1.1 and R301.1. The following comments should be addressed: a. A ledger connection should be included between the addition floor and the existing east building wall. b. Multiple beam connections to the supporting framing appear to be missing. 03200 Cedar Street 425.257.8810 everetteps@everettwa.gov Everett, WA mm 1 425.257.889 fax ® everettwa.gov/permits Pne4N5
