Shear tab welded to supporting member AND supported member

[Lion06]

Does anyone see an issue with welding a shear tab to both the supporting AND supported member? AISC only provides a procedure for bolting to the supported member. Is there a reason for that?

hokie,

A shear tab is a plate welded to the column and usually bolted to the beam web. Field bolting is more practical than field welding, so that would be the norm. In the event that bolt holes do not line up, would you not still consider field welding to be acceptable?

We use this as a field fix as well as a way to transfer seismic forces, welding the shear tab to both beams or beam column.

BA,

It is just the terminology that is different. In Australia, we just call it a shear plate or web plate. The word "tab" sounds a bit flimsy, but as long as everybody knows what it means...

As I stated above, I have no problem with a welded-welded shear "tab" to solve a fitup problem.

hokie,

Thanks, I tend to agree. I would prefer the welded/bolted connection but would settle for welded/welded if required by other factors. There should be enough elasticity in the welded connections to accommodate normal beam rotations.
