Joining two rsjs

givemestrength · 12 Mar 2011

We have an 18 foot square lounge with a rsj running through the middle. Whoever built the extension put two rsjs accross the span with a brick pillar in the middle to support.

Is it possible to joint the two rsjs so we can loose the pillar? If so is this a rewlatively easy pricess once access is gaines to it.

Do you mean they are parallel? If so then the brick column is there for support an no, you can't just remove it. A bit more info wouldn't go amiss!

It maybe wise to get a structural engineer involved.
Removing the pillar and joining the RSJs together will be compromising what you have.
The load being supported and the spec of the RSJs, need to be evaluated and removing the pillar could well mean replacing the two RSJs for new.

Hi

You would never stitch two rsj's together in the manner that you are hoping and as already mentioned you should get some advice from a structural engineer.

Do you mean you've got a brick pillar smack bang in the middle of your lounge??

Anyway, it is possible to splice RSJs using bolted connections so that they are effectively continuous, but of course once the pillar is removed the span will double, and it's doubtful the section size would then be adequate to take the load.
Furthermore, attempting to splice a beam whilst it's in position would be more difficult than propping and replacing with a new beam.

Obviously this will need to be designed by an structural engineer.

Very much doubt if steels have been designed to span 5.5m opening, that is the reason for pier. Need hefty old chunk to span in one..
Splicing together. We often do this but steels must be touching and our old SE will only allow us to splice one third in.
Consult SE.

He's trying to get a bit more info, thats why he has posted a question on here duh! You best tone down your attitude FMT if you wana stick around!

tone it down yeh.

Like said above, the pier is reducing the span of the two beams.. if you wish to remove it you will need to replace these beams with a larger one designed to span the full distance.. get an SE involved to run some figures and do a sketch for your builder..
