Wood Columns/Trusses to Steel Beam Connections
Wood Columns/Trusses to Steel Beam Connections
(OP)
I have a few wood trusses bearing on a steel beam that is supported by wood posts. Everything is sized accordingly for gravity loads but I do have wind uplift loads from the trusses. Im trying to figure out the best and easiest (to construct) connections for the trusses and wood columns to the steel beam. I was thinking a combination of bolts, angles, plates, and maybe some welding but I would like to stay away from welds if possible. Any suggestions here?

could be just me at the end of the day and a couple of beers,
but more info would certainly be helpful, and your attachment provided little in light of the connection conditions....., a sketch of the actual dimensional relationship between your " connections for the trusses and wood columns to the steel beam." would be helpful.

If it were me, if I'm using a steel beam I would just use some 3" pipe columns at each end and weld directly to the bottom of the beam. Another option would just be to go all wood with a glulam beam and attach the beam and column with a Simpson column cap with adequate uplift capacity, would also simplify the truss connections. If you really need to go steel/wood then I guess you could fabricate plates or angles onto the bottom of the beam and bolt into the column, you would need to place the bolts a minimum of 4 diameters from the top of the column for partial uplift capacity and 7 diameters for full uplift capacity.

I'm not really sure on the uplifts if they are net or not; I'm grabbing these loads from old truss drawings with limited info. They do seem high but one of the trusses is a girder truss with a long length of jack trusses attached hence the high Gravity and uplift.
He is building this himself and has no construction experience at all; I heavily advised against this but he didn't care. This is why I am trying to avoid welding and anything else that would make it more difficult than it already is. I was thinking what you said about the bolts into columns but I will need to toss around some ideas for the trusses. Thanks for the advice dnlv!

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

Easier Steel Beam to 4x6 connection. Wrap Simpson CS14 coil straps over steel beam ends and nail straps to each side of 4x6 post. That came to me after all the great tips on this thread. Still tossing around the easiest steel beam to truss connection. I think the same straps might work just depends on how the truss chords are oriented at each truss bearing location.

Meh. I think that you'll always have some slack in that and that would make me wary of using it for rotational restraint of the beam end. Perhaps if the truss to beam connections can be considered to provide twisty restraint.
