Return Period for Wind Loading

Return Period for Wind Loading

Return Period for Wind Loading

(OP)
Does anyone have a quick method or adjusting the wind load based on a return period less than that of the normal 30 year, 50 year or 100 year durations?

Thanks in advance,

Dik

RE: Return Period for Wind Loading

I thought it was 1.0 for 100 year and 0.7 for 10 year.

RE: Return Period for Wind Loading

ASCE 7 Commentary for Chapter 26 goes into return period comparisons in their explanation of the change from 50 year in 2005 to the 300, 1700, etc. in 2010.

Thanks, gentlemen...

A search on the web I found this, Link. I think you can find similar record for the local that you are interested in.

RE: Return Period for Wind Loading

ASCE37-14 has wind speed modification factors for return periods under 5 years.

Thanks very much, I think that was the formula I had seen or one of the same form. I'll check the NBC tonight.

Thanks to you also... I'll try to dig up a copy and see what it says.

Found a copy... it has the info I can use. Thanks.

skeletron:
I've coded the formula into SMath and will play with it this evening.

Thanks, gentlemen

RE: Return Period for Wind Loading

Just an FYI @dik: V is in m/s. They define q = 0.00064645 V2 in the previous page. q is in kPa.

Thanks skeletron, that was my next step... I work in both SI and Imperial, but think in Imperial... just too old. I'll post the SMath program when completed... have some real work to do now...
