Dear All:
I do experience with one irregular shape building before. The shape of the building is something like Burj Dubai (three wings). What i did is by assinging the axis of wind at every 10 degree interval. Eventually, i have 36 wind direction.
Then, design all the vertical element for the worst case.
Pls correct me if i am wrong.
