Addition REVIEWED BY CITY OF EDMONDS € BUILDING DEPARTMENT Structural Calculations (Lateral System Only) 8223 2001" Street S.W. Edmonds, WA 98026 Snohomish County Sidesway Project No. 21069.02 Prepared By: SIDESWAY ENGINEERING llillizl Beebe Residence Addition November 11, 2021 Project No. 21069.02 Project Description Sidesway Engineering was retained by the homeowners to perform lateral analysis and design as necessary to obtain a building permit for the proposed 2nd story addition to the existing single-family residence located at 8223 200th Street S.W. in Edmonds. The gravity system design was performed by J3 Architects. The proposed addition will add two bedrooms over the living and dining rooms, and will be constructed above the existing scissor trusses to avoid disruption during construction. The new roof will be framed with pre -manufactured trusses spanning to stud bearing walls and the floor system will be conventionally wood framed with sawn lumber joists. The addition will bear atop existing stud walls landing on the existing continuous exterior footings. Refer to the 33 calculations for additional information on the proposed gravity framing system. The lateral force resisting system consists of sheathed roof and floor diaphragms spanning to wood stud shear walls around the perimeter of the house. Some of the existing exterior walls are being upgraded to resist the lateral loads resulting from the addition. All dimensions were provided to us on the J3 architectural drawings. These calculations are a revision to the original calculations issued in September due to the roof framing changing directions. The shear wall and overturning calculations have been updated to reflect this. Scope of Work Provide lateral calculations for the proposed addition as required to obtain a building permit. Redline lateral framing requirements onto the architectural plan set. Provide typical framing details as needed. Design Criteria 2018 International Building Code (IBC) 2018 International Existing Building Code (IEBC) ASCE 7-16 Minimum Design Loads for Buildings and Other Structures Applicable Material Reference Standards (ACI, AISC, NDS) This is a Risk Category II structure designed for the following loads: Dead Loads: 15psf (roof), 15psf (floor), 9psf (walls) Snow Load: 25 psf Live Load: 40psf (floor) Wind Load: 100mph, Exposure 'B', KZT = 1.0 (refer to wind loads) Seismic Load: R = 6.5 (wood s.w.), Site Class D, SDC D (refer to seismic loads) Project Summary The lateral system for the proposed 2nd story addition to the single family residence as designed in the following calculations conforms to the 2018 IBC and IEBC. Refer to the calculations and structural sketches for lateral force resisting system requirements. Refer to the 13 calculations and construction drawings for all gravity framing. Disclaimer This calculation package is based on the documentation that was available to us. Sidesway Engineering did not perform a complete as -built to verify the accuracy of the provided data and we should be contacted if there are any discrepancies with the assumptions contained within these calculations. We assume the structure has no known deterioration or damage that would adversely affect capacity. 20305 871h Avenue W. Edmonds, WA 98026 SI-DE5WAY (425) 673-4160 ENGINEERING NIt -rC,- �.
