category 4 hurricane
is here anybody to tell me design wind speed using ibc 2000 for category 4 hurricane.thank you.
by definition from the saffir/simpson hurricane scale:
category 1: winds 74-95 mph, storm surge 4-5 ft
category 2: winds 96-110 mph, storm surge 6-8 ft
category 3: winds 111-130 mph, storm surge 9-12 ft
category 4: winds 131-155 mph, storm surge 13-18 ft
category 5: winds >156 mph, storm surge > 19 ft
eureka, thank you very much.
i think the saffir/simpson hurricane scale using 1-minute average wind speed, but ibc 2000 using 3-second wind speed. do you know how to convert them? thank you again.
