Can someone explain how and where to apply the wind pressures calculated from MWFRS & C & C using ASCE7-16 please?
This is the first time I am trying to design a mono-slope roof open frame structure to place solar panels on top.
I have obtained qz = 18.43 psf for C &C with EQ: qz = 0.00256 Kz Kzt Kd Ke V² (lb/ft²)
I also have the wind pressure for Load Case A & B for 0^ & 180^ Direction for MWFRS
Then I did the C & C computation and obtained NET PRESSURE COEFFICENTS, CN
and wind pressure for three effective wind areas ≤a², > a², ≤4.0a², >4.0a² per ASCE steps.
See attached.
Is the wind pressure from MWFRS for the design of members like purlin and that from C & C use for the design of its fastener?
How would I used those data or What should I do next? I don't know how and where to use them.
From an earlier posting, I believe the wind pressure from ≤a² is for the roof deck and >4.0a² is for purlin. what is the third one for?
Does that mean, say, the pressure in negative psf is used to select a fastener like bolt to resist uplift?
Thanks
