Column top plate
New construction inspection today in a township that I'm not familiar with the AHJ.
Top plate has only two bolts and no welds (that I could see). Would you report this as an inproper support?
Thanks,
Jeff Beck

Re: Column top plate
Without checking the approved plans and/or spec sheet there's no way to tell.
Basically I see nothing wrong with a pair of bolts, but like I said, only the PE who drew that detail would know. Describe, disclaim and defer when in doubt.
Your a generalist.

Re: Column top plate
Much of the time I find the bolts loose but never have a I seen a problem as a result. I tend to ignore it.

Re: Column top plate
Jeff, that 'I'-beam will hold up a hurd of Bull-Elephants (figuratively).
With that said, take the words of Jerry Mc. as being right-on target. There is absolutely no-way of telling what the engineered design of this support required in the way of anchoring. If you found something in the way the anchoring was done that causes you concern, by all means.... identify those concerns and document what you found and why you believe they are of concern.

I've been in structural steel for 30 years, thats a pretty typical connection

Re: Column top plate
Question for the more experienced:
Would there be an issue with lateral movement in that column? The end of the I-beam doesn't terminate in a pocket in the foundation and the beam doesn't appear to be attached to the floor joists at all. I don't like it when the only thing stabilizing the assembly and preventing movement is the weight that it is supporting. I know that there is a-lot of weight on top of this and it would be hard to do (unless this is in a garage), but I can visualize a side impact to the post bringing down the house.

Re: Column top plate
I'm curious about the footing, or is the column just sitting on the slab

Re: Column top plate
After looking at the picture a little closer it appears the column cap plate is not the same width as the beam flange which is a requirment

Re: Column top plate
Speaking of columns, these two had me doing a double take this morning, side clearances were about the same in both parking stalls...

Re: Column top plate
As an engineer myself, I would defer to a structural engineer. There is not enough information here to make a determination. For one, the beam is off center, no stiffner (could be required, or not).
