How to find a response for a pinned-(pinned+ torsion spring) column with sinusoidal axial load?

I am unable to decouple the equations in space and time using variable separable method, with one end pinned-other end pinned with torsion spring as boundary conditions.

Can anyone please help.

Good day.

I am working on a dynamic post-buckling problem.

I wonder if it is possible to simulate dynamic post-buckling of a column with pinned-pinned boundary conditions with an time varying (sinusoidal) axial load in Abaqus.

Thanks.

Good day.

It is known that the if the coloumn is long and slender enough, then under axial compressive loading, the column buckles..

But i am wonder, why buckling happens at all?

Can anyone put a light on this.
