how can i determinate the interaction diagrams of a generic rc section under n,mx,my?
thanks

check out our whitepaper library.
for bi-axial bending you will need to assess the moments in each direction (both x-x & y-y) and design for single axis bending but with an increased moment.  this will allow you to then construct your mn interaction diagram.
you concrete design code should outline a procedure for this.  the place to look is under biaxial bending of columns. it is too protracted to type out the procedure here.

have you some file wich describes the procedure?
