Pushover analysis for masonry structures

[miwilhel]

Hi,

I am trying to model an unreinforced masonry shear wall by a frame system with lumped plasticity in the hinges to perform a pushover analysis. Since the shear capacity of unreinforced masonry wall piers depends on axial load and bending moment, it is important for me to add a new material law for the zero length element.

1. Did some one already model frames with hinges considering a P-M interaction?

2. Is there any NDmaterial or SectionForceDeformation law already available, which could serve me as an example for my masonry material law?

Thank you

miwilhel, did you manage to work it out?
