Converting Basic Wind Speed 50-year Return Period to 2-year Ret Period
Converting Basic Wind Speed 50-year Return Period to 2-year Ret Period
(OP)
Can anybody help me how to convert 3s gust basic wind speed at 50 year return period to 2year return period. I am considering 2 year return period since the structure is temporary to be removed after 2 years (max).

This is a structure which will only be in service for 2 years maximum. However, I am also concerned with what proper reference to use since I am using BS6399 for the wind load calculation. Do you think using ASCE reference to a BS-based calculation will be acceptable? I cannot find any reference in BS Standards for this basic wind speed conversion in respect to return period.

I am using ULS. But if I am going to use 20+ year return period, is this practical, because in 2-years time the structure will no longer be in service.
Do you have any reference for this conversion in Middle East Area using British Standards. I am using BS6399 for the Wind Load Computation.
Thanks.

Sorry I don't have any references for that area. Can you ask a senior engineer in your company?
