Lateral Rotational Failure 1

[cpmje]

I recently read about a building which is said to be failing due to a "Right Lateral Rotational Failure." Is this a term used to describe a failure from having only 3 sides of a 4 sided building braced? Or is there more to this description?

I expect it is a true rotational failure
and therefore complete and based on a simple complex of shear plane in a basal system, rather than a lot of interactive system failures, or a false rotation which may be actually a cause from anoterh source
sorry running out of web load time but that is probably it
ask Structural Soils Ltd Bedminster Bristol they do a lot of foundation site in 'orrible materials and are very good at it especially wet, silty ground

Thank you for your input. I had thought the "right lateral rotational failure" described a building failure mode rather than the soil below.
