Re: Holes in Steel beams

[Subject Prev][Subject Next][Thread Prev][Thread Next]
OWSJ are analyzed as discrete chord and web elements whereas a beam with a
hole is usually analyzed as a single beam element by standard means.

I am surprised at the response from AISC. The guide provides appropriate
conditions to avoid extraordinary engineering effort. Drill and reinforce
but the pipe may not be the appropriate reinforcement.
