Number 1, I prefer a 4 bolt base plate with as wide a spread as possible using headed anchor bolts (uplift or not). The ironworker in me prefers shooting in a stack of shims in the center of the base plate. The column is placed on the shim stack and anchor bolts. For safety I suggest (engineer/iron worker hat on) that the iron workers drive shims at the perimeter of the plate mid way between anchor bolts. Harold, If you don't mind, can I ask you to elaborate on this a bit? How thick is the gap for the shims and grout? How do you ensure the base plate has complete grout under it with all these stacks of plates in there? If there is a stack in the middle, and a stack between each pair of bolts on all 4 sides, isn't it possible to have a void in the grout in an area between these stacks of plates if the iron worker isn't very meticulous in his work? Yes, I know it can happen with a double nut case as well, but with a clear opening between the bolts hopefully packing the grout will be easier. If it is not copyright protected :o), and since attachments have worked in the past, can you attach a typical detail to a file which illustrates what you do? Thanks. __________________________________________________ Richard Lewis, P.E.
