RISA 3D, Load Bearing walls only (NO shear contribution)

[Diego S]

I recently acquired RISA 3D and am using it to analyze a building with wood framing shear walls and load-bearing walls. There are some walls that do not contribute to the main lateral resistance system, so their lateral rigidity should be excluded from the model. How can I neglect the lateral load in RISA 3D?

If you are applying lateral loading via a diaphragm, you can detach the wall nodes from the diaphragm:
