cover steel plates for tube column-column connection

[AhmedJ.J.]

Hello all,

Can anyone please provide me with a reference or any information about using bolted splice plates for connecting two SHS (tube) steel columns? like the case with the I-sections. I found that SHS columns can be connected only using end plates or weld, but I couldn't find a reference regarding using bolted splice plates.

Thanks,
Ahmed

Well bolted splice plate have the obvious issue of needing blind bolts or potentially through bolts with compression pipes. Both quite expensive options. But if a splice connation is what you need then they can be accomplished with appropriate use of the above and normal connection design approaches.

The other option is a simple sandwich plate design if you don't need moment capacity and a pinned connection is suitable. Just watch out for buckling issues.

Look up Shurikan bolts by Atlas Bolt. Could probably do the same thing by tack welding in regular bolts.

You wouldn't use something like :
