Spliced moment connection in Channels
Spliced moment connection in Channels
(OP)
I have a client who has a 9' long channel and needs it to be 12'. It will act as a beam with a uniform load and be pinned on each end. For now he plans on welding a splice plate to connect the two channels (a 3' piece and a 9' piece) on one side of the web and on the top of the top flange and bottom of the bottom flange. Does anyone have any literature, example calculations, or ideas/concerns regarding this concept?
thank you.
thank you.

are you sure the channel section is good for the extra span ?

rb1957 - the channels are 3/16" thick, 12" tall, and 4" flanges - its a custom shape and the material is unknown so I assume A36 for now. I modeled it in RISA and the new span is easily adequate for the small applied loads. I more hoping for something technical that I can use besides my "engineering judgement" in case I have to provide calcs for city comments.
thanks again

Real simple and works...

Yes.

I second Hokie's YES. The weld metal and the HAZ will be as strong or stronger than the base metal if it is a good weld, properly made. This is done every day, intentionally, on much bigger structural members than an 8 or 10" channel. I've done 20' deep plate girders with 48"x5" flanges and 1.5 or 2" webs all full pen. splices and tension welds. They tested fine and are still standing and producing electric power.

Steel is a marvelous material.

But only where fatigue is an issue, otherwise yes.
