Steel beam header connection to glulam column (post frame building) 2

[TroyD]

I have a post frame building with a 36' sidewall opening that requires a steel beam due to the span and loading. I'm looking for some input on the method of connecting the beam to the column. I've read discussions for this topic here on this board. Please see the attached sketch. The required beam is a W24x62, and the end reaction is ~28k. I would prefer to bolt the beam to the side of the column, it seems far more stable than bearing on top. The 24" beam depth should be adequate for the required number of thru-bolts. The glulam column/jamb is a 7-ply 2x8 due to the large axial and wind C&C loads. The wall height is 18'. I know the NDS 2015 has a section on glulam columns and the required strength reductions for bolted connections, but I have not looked at in-depth for this design yet.

Here is a link to a site illustrating the same connection: (see main photo)

Any advice on this connection method is appreciated.

TroyD - I like your detail and the steel plate on the back. Considering the load, I would add thru-bolts with plate washers as shown to supplement integrity of the the glued laminations.

Edit: On second thought, why not use the detail but add a steel or wood column under the beam to make a stepped column.

I'm a fan of SRE's afterthought. Use the glulam column for lateral, provide a strictly gravity load column directly below the steel beam.

I agree with the other posters suggestions, but would not put a steel plate on the back. You will never get the holes to line up without wallowing the crap out of the holes in the glulam.

XR250 - You are right, I did not consider bolt alignment.

Jayrod - Thank you.

What does the glulam column look like above the W beam connection ?

I would be keen to take SRE's detail and also put a post under the beam (similar to how small timber openings are framed with a king stud and a cripple stud)

belts and braces approach.

Agree with the column under the beam. But I wouldn't use end plates. For erection purposes, and so the dimensions don't have to be exact, I would just use a tee, or perhaps an angle, bolted to the column and to the beam web.
