If the reinforcement is not distributed in a rotationally symmetrical manner (i.e., radial and circumferential bars), of course it is not possible to model it exactly using an axisymmetrical model. You have to make an approximation, e.g., select a cross section (wedge slice - tort like) and define the radial and circumferential bars (or smeared reinforcement) corresponding to that section.
Please note that in axisymmetric models, radial reinforcement bars are defined normally, i.e., by lines connecting points, only the circumferential bars look like points.

Another option is to do the modelling in 3D, representing 1/2 or 1/4 by making use of 1 or 2 symmetry planes.
