Modeling Soil around pipeline with stiffeners in abaqus

Hi there,

I never worked with stiffeners in abaqus and now I should use theme. I want to  model soil around pipeline with stiffeners. The stiffener behavior has 3 nonlinear components (x,y,z direction).

Problems:
1-I  don’t know which connector section should I use.

2- in property definition how should I introduce nonlinearity( e.g. different tension and compression behavior)
3-as I know abaqus has feature with name “wire to ground”, but it just allow to select one point each time. Consider I want to attach every point on outer surface  of a pipe (shell) to ground.is there any solution?
 

Tanks if you could help me on this problem.

Best reg.
