Poland, PE <br /> STRUCTURAL REVIEW COMMENTS (Round 2) From Email dated 7/9/21 <br /> 1. The"except as follows" are for the Base Plate Design (and anchorage) and Shims. <br /> Section 15.5.3.5 you note does not exist. I assume you meant to refer to Section <br /> 15.5.3.3 where R=4 is noted. This section is an Alternative to using the ANSI/RMI <br /> Code. The rack design industry uses R=6 for the down aisle loading. <br /> 2. No response needed. <br /> 3. The spreadsheet software I use has not been updated to easily show the <br /> overturning reactions with the overstrength factor of 2 to apply to the anchor bolt <br /> design. I increased the shelf loadings by a factor of 2 to simulate the seismic shear <br /> loads at each level. This would be equivalent to applying a factor of 2 to the load <br /> combination. I have added another sheet showing the shelf loads associated with <br /> the overturning and shear loads. See page 25A in the calcs. <br /> If you have any questions, please feel free to contact me. <br /> Sincerely yours, ECE I,., n <br /> DAVE POLAND ENGINEERING, LLC RED <br /> v <br /> David S.
