That's a good question,
It's time to ARSAP team to include this option in oder to complete the solution for seismic desing calculations, we can start by doing it for rectangular shape in a first time,and after for the other configurations. That would really help ARSAP users,still also waiting for RC desin of diferent shpae of pile cap in oder to complete de foundation design modulus.
If you are able to indicate any reference that describes the way of designing walls under bi-directional bending and axial force I would be much interested too
Such design is currently not supported in Robot.
I find the theory column. But I do not quite understand, the solution of the column.
you can provide theoretical royal adjust 3D calculated column???
I'm not sure if I understand your question. As far as I can see these formulas are for calculations of bending moments based on arm of forces (forces in each of reinforcement bars plus force in concrete) where z is the distance to the neutral axis.
