On June 24, 2021, overnight, the Champlain Towers South, a 12-story oceanfront condominium in the Surfside suburb of Miami, Florida, partially collapsed. This collapse simulation was performed based on currently available data, eyewitnesses and video accounts. …
This study demonstrates the collapse mechanism by assuming the following plausible hypothesis: According to the data, the basement deck has shown signs of prolonged soaking for many years. The problem has not been sufficiently corrected locally and has not been corrected in its entirety. The mooring weakened the deck ceiling to such an extent that the basement piers pierced the deck where an additional load had peaked in the planter area.
The simulation does not quite correspond to reality on one point: the wing remains tottering for a few seconds in the real images, but is brought down more quickly by the center which collapses in the model.
I am fascinated by these (as well as by similar recreations and simulations of the 9/11 attacks), not least because of the dehumanization of the means at the very human end of understanding.
Here is the simulation of the same researchers of the collapse of the Aricebo telescope:
