Thanks to everybody. I defined the wind loads manually on claddings as Artur suggested. But still there are a few problems.
1. If there are shear walls in some parts of a face, should I need to draw cladding over the shear walls also or I can stop at the beginning edge of shear wall?
2. After I defined all the wind loads, it takes too much time to calculate. Before applying wind load it took 5.5 minutes, but now it takes 20 minutes. And most of this time is consumed in "applying loads" stage. Is it normal, or there is any problem?
I mean, upto now I only defined loads for each cases separately. When I combine them, then it will take even more time.
