Re: Foot bridge collapses at Florida university, several killed - ka jowct - 03-16-2018 I hope that the Hudson Yards development on the west side of Manhattan is being built with a healthy respect for wind. Wind along 11th Ave. is for some reason noticeably worse than it is along the East side near the East River.

Yes, there is a lot more that could be said than my abrupt summary. Here's an official report: Investigation of the Kansas City Hyatt Regency Walkways Collapse.

Was that the one where the change put a concentrated load on an upright, which then took all the weight instead of it being distributed across several uprights? Or something like that? Also, I'm astounded to think that the bridge essentially couldn't support its own weight, considering how little pedestrians using it could have weighed in comparison to the structure itself. Better explanations out there, but basically the load from two walkways was supposed to be carried through the same continuous piece of metal secured to the ceiling, but they built it such that the lower walkway was instead secured to the frame of the upper walkway which was not designed to carry that weight.
