RAM Frame Question

[cookyb]

Does anyone out there use RAM Frame for modeling CMU shearwalls? If so, what do you use for Poisson's Ratio when laying out the material properties?

Thanks!

I would use Poisson's Ratio = 0.2.

That's the default (and what I've been using). Do you know of any literature that might back this up?

I've seen published values for concrete of 0.15 - 0.25. Since a conrete masonry wall assembly is all concrete, mortar and grout, it's all basically concrete. 0.2 is still a good number, although I do not have specific backup. Just Google it and I'm sure you'll find some references.
