Mr. Carlos Alvarez <br /> 3rk Architecture Design <br /> Plan Check Number: B2107-004, First Building Review <br /> July 13, 2021 <br /> 4. The columns resist flexural load in both principal directions, and therefore effectively form the <br /> lateral system in two orthogonal directions. The columns and their connections should be <br /> designed for 100% + 30% orthogonal loading. See ASCE 7-16 Section 12.5.4. <br /> 5. The seismic load should include a vertical seismic component concurrent with the horizontal <br /> loading. The vertical component should be applied in both directions; the upward force is <br /> anticipated to create the worse-case loading for the columns, base components, and <br /> anchorage. See the seismic load combinations of ASCE 7-16 Section 12.4.2.2. <br /> 6. The columns may have protected zones depending on the revised system selected, such as the <br /> base of the column for special cantilever columns per AISC 341-16 Section E6.5c. Holes, welds, <br /> and other connections are not permitted in the protected zones. The extents of the protected <br /> zones should be shown in a detail. See IBC Section 2205.2.1.2. <br /> 7. It is anticipated that a special seismic system may be used, such as the special steel cantilever <br /> column system of AISC 341-16 Section E6. The following comments should be addressed: <br /> a. The design should comply with the requirements of ductile members where applicable. See <br /> Section D1.1. <br /> b. The columns should comply with the aspect ratio limits per Table D1.1. <br /> c. Design and detailing for the column base connections, including but not limited to the base <br /> plates and welds, are required to be designed per Section D2.6. <br /> d. Design of the columns considering seismic overstrength. <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 with <br /> 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\2021\B2107-004—Rl.docx <br /> 3200 Cedar Street © 425.257.8810 O everetteps@everettwa.gov <br /> Everett,WA 98201 425.257.8857 fax everettwa.gov/permits <br /> Page 3 of 3 <br />
