You should consider using other material models for your steel. ReinforcingSteel is very unstable.

Define a separate time series and load pattern for the wind load, in addition to the ground motion and uniform excitation

You are hitting zero stiffness on your p-y curve (you have two points with same p values 4.61E+04, 4.61E+04) and the system of equations is singular.

You haven't really shown / provided enough information for someone to know what the issue is. I know for a fact that the section aggregator works for shear, so there's something wrong with your model or your results interpretation. I recommended starting from zero with an elastic cantilever because ...

I don't know what you're showing via the screenshots.

Build a simple cantilever with elastic sections, then aggregate shear. Don't start from someone else's script. Do it yourself, from zero.

Try a simple cantilever with shear deformation and build up from there.

Probably a modeling issue. You have to provide more details.

You can dereference a list in Python by putting a * in front.

It is not uncommon to use different algorithms. Usually 'Newton' is sufficient, but you can switch through other algorithms. There are better switching strategies out there though. Search for "OpenSees smart analyze"
