New Steel to Existing - One Sided Connection
New Steel to Existing - One Sided Connection
(OP)
I am connecting a new steel beam (w8) to an existing steel beam. The new beam will be accessible for connecting from one side only. The loads are small, about 5kips shear (no moment). What is the best connection to do this. Tack on a backing bar and then do a cjp of a shear tab to the existing beam? Welded single angle connection? Access is pretty tight for the work.

SteelPE - That's what I was thinking but what about the weld of the tab to the existing beam from one side only? I'm not too hot on my welding but I didn't think that was kosher. I was thinking that I could do a cjp of the tab to the existing beam by having them first weld in a backing bar. Access is very tight though - would prefer the simplest solution.

Rough sketch attached. The existing girder is encased in concrete, the new beam will frame such that the bottom flanges are close to the same height. There is no access from the back side in this view.
I think I'll just ask for cjp and ask the steel guy when the time comes if he has a better idea. I thought maybe I was missing something obvious but it doesn't sound like it.

So if it's a L3 that's 7" long, you remove a 4" x 2" coupon against the new beam and fillet all along that inside edge.
