internal pressure for structural design
internal pressure for structural design
(OP)
hi,
i am designing a plated structure where client has specified to use
design internal pressure as 660mmWc at 67% yield strength.
as i am designing the Structure to LRFD - IS it Required to Increase the internal Pressure to 100% yield strength
i.e. 660/0.67 = 985 mm wc for Design of Structural Members?
thanks

660mm = 25.98" mercury or 352" H2O = 29.36' H2O = 1832 psf. Wow!

It didn't indicate this was a building of any kind.

Client maybe using the old ASD-89 0.66FY bending for beam, which should have been 0.75FY bending for plate.

If the standard code check for ring tension would be 0.9Fy, I'd set the load factor such that (0.9Fy)/Factor=(2/3)*Fy. So your load factor would be 1.35.
