b. how the new proposed footings are transferring load to the micropiles. Please <br /> address if epoxy grouted reinforcement dowels into the existing footings or similar <br /> post-installed construction is being proposed and provide details and calculations <br /> addressing shear transfer and/or flexure, as required. <br /> c. the centerline dimensions of the individual micropiles. <br /> d. eccentric loading based on new micropiles and existing column loads. Please <br /> address,if load sharing is considered in the design of the footings. <br /> e. punching shear effects on the new proposed footing configuration in both tension <br /> and compression conditions. <br /> f. how tension and compression effects are transferring through the new footing <br /> through the new micropile. It appears that a positive connection between the <br /> concrete cap and the micropile is missing as shown on detail 9/S3.1. <br /> 3. On Sheet 2.1, Grid E/1, please verify at the new foundation can support loads coming from <br /> a loading conditions subjected to bidirectional forces per ASCE 7-10 Sec 12.5.4. c urforr-a A. <br /> 4. On details 1/S3.1 & 5/S3.1, these details indicate the new steel columns are to receive new <br /> cast-in-place anchor rods. However, per Sheet S2.1, it appears the columns are being set <br /> on the existing foundations. Please clarify if this is the case or provide design and details <br /> for a post-installed connection. Also, please note that the anchorage should satisfy <br /> requirements per AISC 341-10 Section D2.6 and satisfy the limit states associated with <br /> concrete failures per ACI 318-14 Chapter 18. Please verify. <br /> 5. Please provide calculations and a narrative as required for resolving sliding in the footings <br /> associated with the proposed braced frames. <br /> 6. On Sheet S1.1 General Note 2, please clarify whether the Lateral Analysis Method used for <br /> design is the Equivalent Lateral Force method as it appears that a Modal Response <br /> Spectrum Analysis was provided in the permit calculations. <br /> Sincerely, <br /> Ja <br /> t <br /> s Bronder, PE <br /> As' late Engineer <br /> Pla Examiner <br /> s'--,Rage 2 of 2 <br /> CITY OF EVERETT • 3200 Cedar Street • Everett, WA 98201 • (425) 257-8810 • Fax(425) 257-88 ~7---__---' <br />
