The article literally describes what cause the building to collapse.
> After 7 hours of uncontrolled fires, a steel girder on Floor 13 lost its connection to one of the 81 columns supporting the building. Floor 13 collapsed, beginning a cascade of floor failures to Floor 5. Column 79, no longer supported by a girder, buckled, triggering a rapid succession of structural failures that moved from east to west. All 23 central columns, followed by the exterior columns, failed in what's known as a "progressive collapse"--that is, local damage that spreads from one structural element to another, eventually resulting in the collapse of the entire structure.
Perhaps read more than the headline and you would not think it so "curious".
- Bob67568584 5y agoYes they basically say "it collapsed because the fire was hot and caused a critical column to collapse". It's a childish level of explanation, not rigorous and scientific. It says nothing about how such a thing could occur. I've studied mathematics, physics, engineering at university up to Bachelors level and to me this is a very amateurish childish level of analysis. The report is fluffed up with many pages of serious important looking official boilerplate, surrounding this one paragraph that basically says nothing. It's a tautology. No rigorous analysis in this report. That in itself is extremely curious to me.
