• <br /> • <br /> Mr. Tim Verzal <br /> Carports of Washington, Inc. <br /> Plan Check Number: B1811-013, First Review <br /> December 21, 2018 <br /> 12.The lateral system is ordinary cantilever columns. The columns shall be designed for the <br /> amplified seismic load per AISC 341-10 Section E5.4a. Calculations revising the design <br /> loads and verifying the design shall be submitted for review. See IBC Section 2205.2.1.2. <br /> 13.The cantilever column systems is located along the centerlines of the structures in the <br /> longitudinal direction. The 36-foot canopies per Sheet S3.0 will have a 50% loss of capacity <br /> if a column fails. The 54-foot canopies per Sheet S4.0 may have a torsional irregularity if an <br /> outer column fails. The structures shall be designed considering a redundancy factor of <br /> p=1.3. See IBC Section 1613.1, and ASCE 7-10 Section 12.3.4.2 and Table 12.3-3. <br /> 14.The cantilever columns provide the lateral resistance for both orthogonal direction of the <br /> building. The columns shall be design for orthogonal load effects per ASCE 7-10 Section <br /> 12.5.4. See IBC Section 1613.1. <br /> 15.The cantilever columns shall be designed for biaxial bending concurrent with axial loading <br /> per AISC 360-10 Section H1. The columns and applied loads are different in the two <br /> principal directions, and therefore each direction shall be evaluated. The axial load shall <br /> include vertical seismic load effects per ASCE 7-10 Sections 12.4.2.2 and 12.4.3.2. The total <br /> axial load shall not exceed 15% of the axial capacity per ASCE 7-10 Section 12.2.5.2 ans <br /> AISC 341-10 Section E5.4a. See IBC Sections 1613.1 and 2205.2.1.2. <br /> This review has been performed for general compliance with the building codes as adopted and <br /> amended by the state of Washington and the city of Everett. Corrections and comments made <br /> during the review process do not relieve the project from compliance with code and permit <br /> requirements. The designers-of-record are responsible for a complete design in accordance <br /> with the laws of the state of Washington. <br /> If you have any questions or require additional clarification, please contact us. <br /> Respectfully, <br /> Drew Martin, P.E., S.E. <br /> Associate Engineer/ Commercial Plans Examiner <br /> (425)257-8813 <br /> dmartin@everettwa.gov <br /> S:\BMartin\2018\B1811-013_R1.docx <br /> 0 3200 Cedar Street 425.257.8800 O everettpw@everettwa.gov <br /> Everett,WA 98201 425.257.8882 fax I everettwa.gov <br />
