For projects with floors, when designing side spans, do the columns need to be turned 90 degrees at the wind-resistant columns?
The lower column does not need to turn, the upper column in accordance with the wind column to calculate, if you choose the cross-section according to the direction of the weak axis of the calculation of wind resistance is also enough, then there is no need to turn.Upper column to turn to cross-section can be relatively small, but the upper and lower column node processing is more troublesome.Depends on the specific circumstances of the trade-offs.
