Shear behavior for shear wall

[[email protected]]

The shear wall which is flexural damage (H/L=1.5) is modelled well. However, when the H/L=0.5 and the shear wall is shear damage, the capacity and hysteresis behavior is not acceptable

. Can the shear modulus and shear constitutive relation be defined? Here is the model

Can the hysteretic curve(2000-1000 model which the line is red) be smoth by changing the Analysis?

In the horizontal analysis try this:
algorithm = NewtonWithLineSearch
test -> tol = 1.0e-3
test -> iter = 10

It looks like the way you defined the hysteretic curve for the steel plate gives some problems with the Krylov algorithm.

Other than this, I would:
a) refine the mesh, it's too coarse now.
b) Change the pdf_t. Now it is equal to 1, but concrete is more brittle in tension. try to play with this value ans see what happens to the results
