8. The following are follow-up questions regarding the moment frames proposed: <br /> a. It appears that a yield strength of 36 ksi steel is being used on the project for the <br /> HSS sections. Typical HSS sections are fabricated with a yield strength of 46 ksi. <br /> Please confirm if the intent is to use 36 ksi steel for the HSS moment frames. <br /> b. The beam callouts appear to be conflicting with each other on Al/S3.0, B1/S3.0 and <br /> 5/S3.0. Please clarify which beam callout is to be used in the frame's construction <br /> and revise drawings accordingly. <br /> c. Reviewing the FR connection provided, please clarify using AISC 341-10, which of <br /> the three options is being used to design the FR connections. It currently is unclear <br /> how the details in Al and B1 on S3.0 work together with the updated connections <br /> provided on S4.0. <br /> 9. After reviewing the response calculations, it still is unclear which values are being used to <br /> the design against the uplift in the footing as the values in the hand calculations conflict <br /> with the values obtained from the RISA models. Please clarify and provide supporting <br /> documentation justifying the use of values indicated in the hand calculation. <br /> New Structural <br /> 12. On Sheet 2.1 of the architectural drawings, 5'-0"of 18"diameter of reinforced concrete <br /> extends from the base of the steel moment frame columns. This would appear to adjust <br /> the behavior (due to a change in section composition) of the steel moment frame, which <br /> does not appear to be reflected in the recently submitted RISA model. Please verify and <br /> update the frame analysis as required. <br /> If you have any questions, please email or call me at (425) 257-7287. Upon submittal of the <br /> drawings, your application will be given priority and plan reviews will recommence. All required <br /> submittals shall be sufficient detail and contain sufficient information to ensure that the proposed <br /> structure will be constructed in compliance with all adopted codes. <br /> Sincerely, <br /> James Bronder, PE, SE <br /> Associate Engineer <br /> Plans Examiner <br /> 2 of <br /> CITY OF EVERETT • 3200 Cedar Street • Everett, WA 98201 • (425) 257-8810 • Fax(425) 257-8857 <br />
