(1,464 posts)The sim shows that when you remove the lateral support provided by the floors, the exterior of the building folds up. The building's actual behavior thus suggests that the floors were still in place, helping it keep its shape. The behavior of the exterior walls is hardly "irrelevant" to NIST's hypothesis for initiation and progression. An hypothesis needs to explain ALL the associated features. The behavior of the exterior of the actual building is not consistent with NIST's hypothesis.
Your belief that a non-structural curtain wall 300 feet wide and 600 feet tall is going to be rigid in a NW wind is a real hoot.
Give us an explanation that behaves as the actual building did, instead of an "Other than that, wouldn't you agree it was a pretty good play, Mrs. Lincoln?" argument.
