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
