RE: base plate software

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Yes: be aware of the software that advertise finite element analysis of
steel base plates complete with nice looking color coded stress
distribution. All of this is fine, but to me it indicates that the
developers may have no idea what an engineer needs to perform practical
work. And that might result in other shortfalls down the road. We should
never need to analyze the heck out of a base plate. We should never transfer
bending moment from a steel column to foundation via flexible steel base
plate. If moment transfer is required the best way is to transfer directly
through the flanges of the column via anchor bolts. Base plates should be
designed for vertical loads only. We have enough to worry about without
having to consider the flexibility of a base plate in the load path. At
least this is what my practice is. Design of base plates starts from using a
3/4" steel plate (for various reasons not necessarily related to load), then
should be checked for stresses using the two or three simple AISC published
formulas. Stay away from using 2" plates (or thicker) if you have any choice
at all. Use thick plates with caution. They require special milling and
welding procedures. Try to stay within 1" to 1 1/2" plates if at all
possible.

I am thinking about purchasing the Ram base plate
program - it looks pretty good - any opinions out
there on it or others?
Thanks,
