Base Plate Analysis: 4ft Wide Bay <br />The base plate will be analyzed with the rectangular stress resulting from the vertical load P, combined with the triangular <br />stresses resulting from the moment Mb (if any). Three criteria are used in determining Mb: <br />1. Moment capacity of the base plate <br />2. Moment capacity of the anchor bolts <br />3. Vcol <br /> . h/2 (full fixity) <br />Mb is the smallest value obtained from these three criteria. <br />Fy = 36000 psi <br />Pcol = 15136 lbs <br />MBase = 5833 in-lbs <br />P/A = Pcol/(D . B) = 15136 / (8 . 8) = 237 psi <br />fb = MBase / (D . B2 / 6) = 5833 / (8 . 82 / 6) = 68.36 psi <br />fb2 = fb <br /> . (2 . b1 / B) = 68.36 . (2 . 2/8) = 34.18 psi <br />fb1 = fb - fb2 = 68.36 - 34.18 = 34.18 psi <br />Mb = wb1 <br />2 / 2 = (b1 <br />2 / 2) . (fa + fb1 + 0.67 . fb2) <br /> = (22 / 2) .
