hurricane wind speeds
how do u.s. 1-minute average wind speeds relate to basic wind speeds or 3-second gust velocities used for design?
check out our whitepaper library.
ibc has a chart relating the wind speeds - table 1609.3.1
so the u.s. 1-minute average wind speeds used in the saffir-simpson hurricane scale is the same as the fastest mile wind speed used in the old code? do you have a reference that says this? thanks
there is a rather long explanation on the wind speed definition in the 2000 ibc structural handbook. i can email it to yo if you do not have it. i do not know what the hurricane wind speed is based on for a fact but i think you are right
3 second gusts are about 1.2*sustained wind speeds
