B2301-001 9227 4th Ave W Napa Homes LLC c. The truss design should be reviewed for conformance with the approved construction drawings and the referenced building codes, and approved for construction by the designer-of-record for the approved drawings, prior to fabrication and erection. 17. The project includes end trusses over the exterior wall. The wall framing is not continuous between the foundation and roof sheathing. The drawings should include a bracing detail to resist out-of-plane loading (e.g., wind) on the wall. This is not provided by the manufacturer. Note that truss stability bracing provided by the manufacturer is not intended for this purpose. Calculations substantiating the bracing should be submitted for review. See IBC Table 2304.10.1. 18.The lateral system includes discontinuous shear walls supported by beams below. Calculations substantiating the design of the beams including overstrength should be submitted for review. See IBC Sections 1604.2, 1604.4, and 1613.1, and ASCE 7-16 Section 12.3.3.3. 19. Continuing with the previous comment, the Upper Floor shear walls on the north side of the house are supported by cantilever joists oriented perpendicular to the walls. The joists directly supporting the wall ends are not anticipated to have sufficient capacity to resisting the shear wall chord forces. Only the joists directly supporting the wall ends should be considered to resist these loads; load sharing with adjacent joists is not allowed. Modifications to the framing should be performed as need to complete the load path. Calculations substantiating the supporting framing should be submitted for review. 20. The shear wall holdown design for the Type"HDU5"anchors has not been provided in the structural calculations. Calculations substantiating the holdown design should be submitted for review. The design load should be determined per ASCE 7-10 Section 12.4.3.2 Equation 7 including the vertical seismic load effect per Section 12.4.2.2. The seismic holdown forces should be calculated even when wind controls the lateral design. See IBC Sections 1604.10, 1613.1, and 1901.2, and ACI 318-14 Section 17.2.3.4.3 This review has been performed for general compliance with the building codes as adopted and amended by the state of Washington and the city of Everett. Corrections and comments made during the review process do not relieve the project from compliance with code and permit requirements. The designers-of-record are responsible for a complete design in accordance with the laws of the state of Washington. If you have any questions or require additional clarification, please contact us.
