Re: Hurricane Wind Speeds

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Average over 60sec look in the commentary in ASCE 7 for correlation between
the various wind durations. In the '95 version it's Fig6-1. I was surprised
that the 120mph (3sec) I design for is only a Cat1-Cat2 hurricane.

Subject: Hurricane Wind Speeds

What criteria is used for the hurricane wind speeds that are reported by the
National Weather Service?  Are they 3-second gust?  fastest-mile?  something

I'm just trying to correlate the wind speeds that are being reported to what
we design for per the ASCE 7 code.
