what is the best connection for this? round timber pile to steel beam? 8

[delagina]

I can't figure out the best connection to do this.
if the timber pile was square, I could have used seat angle at the bottom of the beam.
but I prefer to use the more common round timber pile.
is there a round seat angle?

I could also install anchor bolts on top of the pile and bottom flange of the beam?

Did a lot of these for former employer. Standard detail was a square steel plate over top of pile, & 2 steel straps welded on underside of plate, running down 2 sides of the pile. 2 bolts through straps.

For 12" pile butt, use 18" sq plate x 1/2". Bars usually 3x3/8" with 3/4" bolts.

Shims can be placed between plate and steel & welded to make up for accuracy of chainsaw cut on pile.

We treated top of pile with hot creosote cover with asphalt roofing nailed down around sides of pile. Bolt holes were treated with hot creosote applied with a bent funnel. (Creosote not so popular now a days!)

Don't use lags in exposed wood connections - they loosen.

Yep. We work a lot around the logging industry and have done a lot of work on wood pile supported: lumber mills, logging and rail bridges and docks and that detail is the one most used. Not pretty, but hard for the average millwright to screw up. In the environments we are working in; pretty is not usually considered an issue.

If the pile alignment is ok then a full length (over the entire pile bent) single bent plate or sometimes a channel with the 3/8" plate straps is used. Steel shims as necessary. The straps are just welded on the outside of the channel.
