steel beam to wood column connection
steel beam to wood column connection
(OP)
Can anyone recommend a typical detail for attaching a W beam to a wood column?
Also, when inserting a steel drop beam below existing wood joists (e.g. as in replacing an existing stud bearing wall), is it possible to brace the compression flange of the steel beam with the wood joists? If so, what is the best way to connect the joists to the beam... wood nailer w/ toenails, clip angle with thru-bolt, some sort of Simpson clip, etc.?

As for the other, I would attach a wood nailer to the top of the beam with Nelson Sill Plate Anchors, and toenail the joists to the nailer, placing solid blocking between the joists. I add Simpson A35's or LPT's to the blocking/nailer connection if needed.

Can't say that is unacceptable....

Seems like a unique approach to attaching the nailer to the beam, but still seems hokey to me...
RE: steel beam to wood column connection
Maybe I am not understanding what you are doing. But what I was "thinking" was a simple I-beam supporting 2x10s (or whatever) floor or ceiling joists.
This detail is what I see quite often. Will the I-beam "slip" - I doubt it - since it is tied into walls or concrete pockets..
RE: steel beam to wood column connection
MiketheEngineer, you have the situation right, and I understand exactly what you are describing, but I think I will prefer a little more substantial bracing connection than the bent over nail.
As far as a wood nailer goes, I have usually specified powder actuated fasteners or bolts. Do the nelson studs (we are talking about Nelson threaded studs, right) have advantages over either of these two methods? Are the studs welded to the beam flange in the field? I wouldn't normally trust residential contractors to do much welding.

Don't forget the 2% rule. It only takes about 2% of the maximum force in a beam to keep it stable. I usually use 5%!!
