Wind Speed for assigning wind load.
Wind Speed for assigning wind load.
(OP)
I've read the wind rose in the city I want to design for, and I got the results of this; 61 km/hr 1 hr/year
50 km/hr 8 hr/year
38 km/hr 43 hr/year
I got the average weight of these three values and I decided to design with 43 km/hr ( the average is 40.3 km/hr exactly )
Is it ok since the 61 km/hr occurs only 1 hour a year ? btw I'm using ETABS for modeling and designing.

In the US, the design wind speed will be specified by various building codes, based on a certain probability of not being exceeded in 50 years time.
If you're in the US, check your local building code, which likely refers to IBC, which in turn is based on ASCE 7 of various years.
If not in the US, you'd need to check your area's legal and building requirements. Maybe tell us where you're at, and some of the forum people might be familiar with requirements there.
For strength design, any of the wind loads you listed would be very very low.
They might be okay for heat loss or similar serviceability issues.

This isn't a real design I'm practicing on assigning wind loads to see the behavior of the building under such loads.
Thanks for all

Wind rose values are measured 10 m above the ground.

(3-sec peak gust in mph*) mean ?

If you design something in Istanbul (Turkey) you need to follow the local codes especially when it comes to loads
