it seems like it should be trivial.... but ..
how much load can be put on a standard perimeter foundation?
for example if there is 6000 lbs on a 4x4 post that sits on a 6" x 12" wide footing (with 3-#4 bars)... and the allowable soil bearing pressure 1500 psf... typically on one design a pad...
i don't think i can use the folded plates for this project. It is a remodel... and there are just to many added uncertainties.
That been said one can still add a lot of extra strength, for not a lot of extra cost... a fancy sink and fixtures probably costs more.
adding xtra nails at top...
Thank you all for your responses. I will talk to the architect and owner.
a few thoughts however..... some frivolous but...
-- i have attached an APA document I just got from APA... Folded Plates.... notice the water stamp 'Use at Your Own Discretion'
-- sags might be kind of cute, if...
I agree with XR250.... but its about what the architect and owner want visually... vaulted ceiling, clear spaces and minimal visual structure. The project is part of a remodel with some of the structure to stay in place.
The things what gets one self into!
Hi KootK , I will be happy to post or send drawings. Is there a limit on allowed size at this site?
Probably there will be 2-cross-ties for a 50 foot long wall, so it will not be all diaphragm transfer. Also, it may end up with partially supported ridge. Also, it is trickier as the 'gable...
Thank you for your very quick answers. The folded plate is what I was thinking about. A bit scary... but as BAretired suggests it is possible in theory.
Thanks, again.... 3 weeks of thinking, it is very helpful to have the ideas of others.
are rafter ties necessary?
assume:
-- a plywood-roof-diaphragm is designed to carry the largest possible in-roof-plane loads.
-- the top-plate of the wall is designed to be an adequate chord for the diaphragm.
-- the gable-end-walls can transfer the the diaphragm-shear at the...
