About nonlinearBeamColumn element

Hi, everybody

How many integration points are appropriately to the nonlinearBeamColumn element.
for example, in my model, the length of element is nearly 6m becauce the model is very large.

and how big area is one concrete fiber for fiber section based on your experience.

Could diameter of reinforce be replaced to according to equivalently area principle.

how the parameters will influence on the simulation results.

thank u.

5 integration points (IP) work well for most of the cases. I choose the number of IP such that the bottom two encompass the plastic hinge.

Regarding the area of the fiber, I think the best is to start with a coarser mesh and then to make it finer until moment-curvature does not change significantly with the change of mesh.
