Computer simulation of the Surfside Tower collapse – .


When the Champlain East Towers building collapsed, a single poor quality security camera on a nearby tower captured the ongoing disaster. Along with a few other clues – a camera clip showing water in the garage moments before, photos of rotting concrete and exposed rebar – it was crucial in helping to quickly understand how the collapse happened . Almost a month later, detailed and credible computer simulations appear, calibrated on indistinct images. [Laurea University of Applied Sciences]


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:
