Just one bolt? 4

[theonlynamenottaken]

OSHA/AISC requires one bolt in solid webbed bracing members for erection purposes, but can the final connection only utilize one bolt? I don't like the idea of any connection relying on one bolt, but this is not my design... just a review. I've searched this site, the web and the AISC manual and cannot find anything stating that more than one bolt is required for bracing connections. (FYI - the bracing is concentric tension only X-bracing using single angles)

Just read the begining.
It says angles

Just as a note:
A bolt in this case will be subject not only to shear but also to the prying force due to the exentricity of the centre line of the angle.

And the instalation. Few good ppoints were made here regarding this. Thanks Men. Verry verry good ones.

Use 2 bolts and have a nice dreams.

rmw,

I had a good laugh with this article. Here's a quote from the article:

"They're not the wrong bolts. They just don't meet specifications for the crane."

hahahaha yeah right!

I wonder how often this crane bolt thing happens and doesn't get caught. I'm sick to death of the purchasing people and construction people who have to be convinced that you really do want an A325 bolt and the bolts you buy at the hardware store ain't it.
