For a Structural Beam Foundation:

Use through bolts, washers, and nuts to anchor the base plate to the flange of the

structural beam (see Figure 9-6). Install web stiffeners to prevent the beam from

twisting. If shimming is required to level the base plates or to keep them in the same

plane, add the shim beneath the entire base plate. For bolting the base plates, use four

M10 or 3/8-16 UNC anchor bolts. For welding the base plates to the beam, use a 3-

inch fillet, 1 inch long on 3-inch centers.

After securing all the top plates and base plates, slowly back out the nut and

centering washer on each hold-down bolt, carefully lowering the top plate and

weigh structure onto the load cells.

After all the top plates are down and applying load to the load cells, make sure

there is adequate clearance between the hold-down bolts and retaining holes. See

Figure 9-7 and Figure 9-8.
