Pole Barn Framing

[mhughes]

I'm having a 36x48x16 pol barn built currently. It's being built with 6x6 PT posts 12ft apart on center, with 2x6 bookshelf girts blocked in between. After the crew left yesterday I looked at it and saw a possible red flag. They notched the end posts out and fastened the truss to the post. On the second bay in, they simply laid the truss on the top 2x6 girt, butted the truss up to the post and fastened it to the post. I have never seen that done. Shouldn't there be a top header plate going around the building set into the posts by notching every post, then attach trusses on top of the headers using hurricane brackets?

Thanks, and I apologize if I'm using incorrect terminology.

Heres how Pioneer does it.

4x6 posts, on 8' Centers. Trusses every 4'. Every truss next to a post is nailed to it then the top of the post is chain sawed flush with roof pitch. Double header beam thingy, 2 by 10 on each side of post.

...photos would help, a lot.

On the second truss/column, are you saying that the truss end hits the inside face of the column? and only has 1½" of bearing???
If this is the case then I'd stop the work. Photos please.

I have a Hansen pole building that is 36x48x14. My posts are 12ft on center and the three interior each side are 6x10. All trusses are attached by notching the posts at the top so that the truss sits directly on top the post. It is then attached to the post with ledger locks. I've never heard of only the outside posts being notched and the others attached to the side.

Hmmm, different ways of doing it..
Not sure were you are located, and what types of roof loading you have to contend with.
Snow load?
I would prefer they used double headers to rest trusses on.
I assume local inspector to approve.
Maybe call on him to come out soon.

I'm no expert, but that looks pretty wimpy to me.

The end looks ok, but the others look cheesy.

No racking resistance at all in the bookshelf girts either.(I know the steel siding will cover racking issues)

Probably fine, just my op.

That's my thought too, but I've never done one or been involved in it before so I wanted to ask around. We get a decent amount of wind and snow so I want it to be stout. Thanks for your input!

We get pretty strong winds and a few feet of snow each year so we made sure to order the trusses to hold that load. No inspector, our county doesn't permit or inspect on auxiliary buildings unless unless used for living space. Maybe I can pay a fee for them to come check things out since my knowledge on this is limited. Thanks for your info!

What is going between those two trusses??? Or is the only trusses the ones on the posts?
Maybe they do things different in different areas, but I cant imagine only having 2xX trusses 12 feet apart. Here, wed put them 2 foot apart max, supported by a double header of adequate height between the posts.

I have seen long spans between the trusses, but the purlins are flipped vertical, not laid flat.

I've worked with a crew that always built them this way. It was up in PNW and we never had a problem with that design.

Pictures make a world of difference. As mentioned, here in the PNW that is a common method of attaching/locating the mid trusses. The bottom chord fully rests on a 2x6 in the same plane and both are attached to the column. The only issue would be the fasteners that hold it all together. The photo shows a handful of nails but I would be looking for some ½" lag bolts or through bolts (all-thread works) in both of the truss members as well as the supporting 2x6.

Thanks for the info and advice. I live in the PNW so it's interesting ou guys mentioned this is what they tend to do here. I talked to the contractor today and They will be using ledger loks and doubling up the top girt and a few other things to secure the trusses.
