Boundary conditions for buckling of column

[karthickaero1]

For fixed-fixed BC's, i have to arrest x and y displ. For simply supported case, i have to arrest y displ. Then my doubt is, while applying force at the end of the column, how the displacement will happen for fixed-fixed column.

You want to fix both ends and then apply loads to them?

 

[karthickaero1]

yeah...that's my doubt...

I don't see how you want to call the ends fixed and apply loads to them simulateously. Are you sure that is what is being asked of you?

I read it as one end being fixed in both x and y, and the other only in y, thus free to move so as to allow buckling, like http://upload.wikimedia.org/wikipedia/commons/5/54/Buckled_column.png" Is that the problem you're describing, karthickaero1?
