Poland, PE <br /> Due to there being no overturning of the cantilever racking at the UMC project noted <br /> above, calculations for the anchors were not shown in the calculation packages. There <br /> is only minimal shear load that is being spread among 4 anchors at each base. <br /> The anchors shown on the drawings as 5/8" diameter concrete anchors with 3.75" <br /> embedment is more than sufficient for the minimal loading. <br /> This applies to Configurations P, T, U, R, and W. <br /> The overturning was checked with the overstrength factor of 2.0 applied to the <br /> seismic loads only (not the dead loads). The analysis results still show no <br /> overturning forces. Only the small lateral shear loads applied to the 4 anchors. <br /> See the attached sheets showing the overturning without and with the <br /> overstrength factors applied. <br /> If you have any questions, please feel free to contact me. <br /> Sincerely yours, <br /> DAVE POLAND ENGINEERING, LLC <br /> .:05 Ff./ <br /> S P OL <br /> David S.
