Block shear

[novembertango88]

Hi all,

Can I one bolt connection experience block shear or does it only apply to multiple rows?

Thanks

I don't see any reason it wouldn't apply to a one bolt connection.

Also, I'm sure block shear can happen to such a connection because I bolted a small angle into a tension testing machine with one bolt and it failed by block shear.

You absolutely will but these will manifest most likely as end tearing conditions.

Ok thanks

Are you talking about a single bolt in shear, or a single bolt in a group of bolts, as shown by Enable?
Enable might be on to something novel and interesting. However, AISC defines the block shear failure mechanism for fastener group perimeter in a group of bolts (or 1 of 1), but not for 1 out of many.

Single bolt in a plate. It's a lifting point. So 1 of 1.
