Default Flitch plates

Hello
Is there any way of doing a timber beam calculation with two flitch plates?
Thanks

Default Re: Flitch plates

Hi Adrian

prosteel does not do flitch beams you need superbeam or eurobeam

having three timbers as a flitch is not too much of a problem I set the
timber to 3 number and design a flitch beam - with the plate I would
say set the thickness to 20mm or any other thickness divisible by 2 and design as normal then split the plate into 2 number 10mm plates sandwiched between the three timbers

To have 2 plates at say 10mm thick x 200 deep would weigh 31.4 kg/m length so it would probably be more cost effective to use a steel beam remembering that flitch beams cannot be spliced so watch the overall weight of the beam

Hope this helps

regards

John

Yeah, I was already in proSteel though so I posted the question here.
I assumed the same people use this as Super beam

I've lost count the number of times I've told the people I draw for that a smaller steel beam would be better than larger section multiple timbers.
"We're carpenters so we work in wood" appears to be the mantra.
