I am looking for confirmation on what this statement means above the C&C results:
"All pressures shown are based upon ASD Design, with a Load Factor of .6"

I am to simply multiply my table of results by 0.6 for use in designing connections, or was the factor already included in the results?
I am getting very high pressures for a 1 story building

thank you in advanced

I take it to mean that the 0.6 has already been included in the resulting pressures. C & C pressures are usually higher than MWFRS pressures and its not uncommon to have pressures over say 60 psf, depending on the size/shape of the structure
 
I thought so too, but I am getting pressures of up to 110psf for a single story building. most products aren't rated for that
 
Are you using ASCE 7-05 or ASCE 7-10? If you are using ASCE 7-10, the wind speeds have increased, for example from 90 mph to 115 mph to reflect ultimate (not service) load conditions. If you are using ASD, you will have to bring your wind pressures down by a factor of 90^2 / 115^2 then multiply that by your importance factor(that resulting number appears to have already been multiplied by 0.6 in your software).
