I understand that the transformer weighs about 400 pounds and is to be attached to an <br />existing 6-314 x 48 glue -lam roof beam no closer than 3 feet and no further than 4 feet south of Column C7. <br />Further, the transformer will be attached using 4 bolts spaced in a square pattem, 30 inches apart <br />horizontally with the top row at 9 inches below the lop of the beam and the bottom row 25 inches below <br />that (or 14 inches above the bottom). <br />The additio tat load due the transformer, the location of the transformer, and the location of the mounting <br />bolts should cause no problems in the beam. The load is generally within the depth of the beam where <br />concentrated loads are normally neglected for calculating bending and shear stresses in beams, and the <br />holes are locate outside the maximum shear stress plane which occurs at 24 inches below the top of the <br />beam. <br />I trust that this information will meet your needs. If you have any questions or require additional information <br />please do not hesitate to call me. <br />Sincerely, <br />R.L. MORRISON ENGINEERING CO. <br />Robert L.
