load bearing support

[rick1976]

looking at removal of load bearing kitchen wall in standard semi house have an RSJ running under floor boards supporting an upper wall.
looking at wall opening underneath this RSJ thus creating a point load !! could i use a catnic lintel or would it have to be an RSJ

rick1976...welcome to the forums. Keep in mind that this is an international forum, so you might want to re-state your question but explain your abbreviations and colloquialisms. That way you'll get more response from a variety of engineers, and absent local code issues, might lead you to a reasonable solution. If you state your location, you might get pointed input on local code issues as well.

RSJ = Residential Steel Joist?

catnic = catatonic nickel? I really have no idea here either...

Is this a mobile home with a mix of light gage steel and wood framing?

masquared48;

RSJ = rolled steel joist. These were originally made in the UK for mining works
but are very rarely used today, though most people here still incorrectly refer to any steel beam as an rsj.
Modern beams (with parallel flanges) are referred to as UBs (universal beams) and UCs (universal columns -
wide-flange beams).

Catnic is just a trade name for light-guage prefabricated lintels. (the vast majoritty
of domestic construction here is masonry inside and out).

That's the problem with an international site. Tell you what - one of the most confusing things is the
nomenclature for elastic- and plastic modulus; here it's Z and S in that order!

RSJ = Rolled Steel Joist or I-Beam.
A catnic lintel is a steel or stainless steel lintel manufactured by the Catnic Corporation. It was devised by one Brian Robinson who named it after his two kids, CATherine and NICholas.

I don't suppose this thread will survive very long because it is specific to a particular residence, but the OP would need to indicate the size of the wall opening and where it occurs relative to the beam. If the opening occurs between bearing points, no lintel would appear to be required.

tony1851 - only makes sense that Z and S are reversed on each side of the Atlantic - after all, in the US we all drive on the "wrong" side of the road correct?
