Good morning. I'm attempting to model wood shear walls using ZIP WALL R-6 insulated sheathing panels. For those who aren't familiar, this type of wall system consists of a wood structural panel with rigid insulation adhered to the inside face (between the panel and the studs). They come with a third party testing certification and diaphragm/shear wall design tables analogous to those in the NDS. They aren't great for shear walls - they aren't quite as strong as an OSB or plywood wall, and because of the placement of the insulation they are actually more flexible than a wall sheathed in nothing but GWB. This is in a moderate wind, low seismic area, single story building so the flexibility isn't a deal breaker. I'm just trying to figure out how to get the strength and stiffness data from the testing group into RISA so I can transfer the loads to the foundation framing (the structure is elevated on an open foundation) with some level of accuracy. Any help would be appreciated. Thanks.
