Lintel to support wall and ridge beam
Lintel to support wall and ridge beam
(OP)
Hi,
I would like to verify if this product
https://www.onesteelmetalcentre.com/~/media/OneSte...
is capable of supporting roof load and double brick wall based on the product spec.
I've attached a diagram and spreadsheet showing the working outs.
http://files.engineering.com/getfile.aspx?folder=b...
Questions I have are:
1. For Lintel L5, should I assume it to be point load over 1.810m span, so the product is ok for use ?
2. according to this website, the force acting on L6 may not be uniformly distributed:

To verify if the product is suitable, should I assume the load to be UDL or point load over 2.260 m or 5.08m ?
Thanks.

This product is an envelope nightmare, be aware that it seriously screws up flashing and is a thermal mistake.
But i do like the creativity in it! i am concerned but I have never seen it before today...
RE: Lintel to support wall and ridge beam
- full lateral restraint.
- equal load each side of the beam.
The first is dubious and the second is highly improbably. + all Eric's concerns.
I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

@EngineeringEric
This product is widely used in Australia to support openings in cavity walls. L6 both ends are supported by the load bearing wall and the 350x350mm brick piers.
The ridge beam is 250UB25.7kg.
I'm not a structural engineer (did one subject in structural engineering during 1st year of an electrical degree many years ago) but trying to see if this design is feasible purely based on the product spec guaranteed by the manufacturer.

I'm not structural engineer, but just want to see what is feasible purely based on off the shelf products.
can you open this file ?

RE: Lintel to support wall and ridge beam
L6 is a three span continuous beam with maximum clear span of 2260mm. To be conservative, you could take it to the center of the piers which would mean the actual span is 2600mm. It is continuous at each end, so the assumption of a simple span is conservative. The reactions from L5 fall only about 250mm from the supporting piers; hence contribute only slightly to the moment. It would seem reasonable to check L6 above W5 using a uniform load equivalent to 2.0m of wall and a simple span of 2.6m.
My concern would be whether or not the 350 wide cavity piers could safely sustain the combined axial load and wind forces. Like hokie66, I am not a fan of cavity walls and would prefer to see the two wythes of each pier tied together sufficiently to cause them to act as a single unit.
