Is that in a location where you occasionally get several feet of snow, followed by steady rain?


 
Well, I'm not a structural guy but I know that doesn't look right...
 
VE1BLL - yes possibly.

Yikes.

It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.
 
Any idea how that came to be? Was the roof raised? Rube Goldberg must have been involved.
 
How long has the building been there?
I just how that it isn't in an earthquake zone.

Self cleaning feature. Hit the roof with a big hammer and whole thing vibrates like a tuning fork, dislodging all the dust. Patent Pending!
 
Looks like they cleaned-out the trash bin as they were putting the finishing touches on the roof supports. Whatever they found, they put to good use.

The load's not 'that' high... and the flanges would nearly produce a fixed end condition with the web... as Ron will tell you, a good part of forensic engineering is determining why things stand up, when they really shouldn't.

In structures where crash energy management is required mechanical "fuses" are common.

But for a roof?
 
One of our engineer's was out shopping with his wife this weekend and took that photo. I've asked him to find out where it was.
On an ethical view I suppose I should forward to the city building dept. and have them review.

The concern here is that the lower column has nothing laterally supporting it except for the web of that WF piece.

It may stand for 40 years but whoever did that should be made to do push ups or something.

Nothing to add except shaking my head... and that piece of WF has a bolt pattern in the web.

Analog spoken here...
 
No one caught this before now?! Not the EOR? Not the building department? Not the inspector? Not the contractor?

Sigh....
 
I'm no structural engineer, but that column looks a little undernourished to me.
