We have been faced with a question, thought to put it on this forum for any comments/guidance If a column has maximum moments about x- axis when earth quack forces are applied in y direction and have maximum value of moment about y axis when earthquake forces are applied in x direction and we make two different load cases to cover x and y direction. While design of column will it be considered as bi-axially loaded column or we will design independently for both load cases as uni axial loaded column to explain my point following is the mathematical form Load case-1 D+L+Ex, it gives P and Myy Load Case -2 D+L+Ey, it gives P and Mxx what will be the design condition? P+Myy+Mxx ( Biaxial Codition) or P+Myy and P+ Mxx ( Check for both cases independently) Please reply
