You asked a question about dropping a weight on a floor and got an answer. A hole (or just deformation). If you drop of series of weights, e.g. columns with spandrels, on a floor, or, if you drop a floor on a line of columns with spandrels, you get a line of holes or a long slice in the floor - as described in the article. The columns are 100 times stronger than the floor and pierces the floor, up or down.
The article is written with courtesy, the NIST has been informed about it, NIST has actually replied (and not complained about the style) and referred to its FAQs Dec 2007 that raises more questions than answers. NIST first, as you know, maintained the upper block was solid acting as a hammer (not being destroyed) destroying the columns below like spaghetti (KE>SE), then it was 6 or 11 floors dropping down (the upper block suddenly lost 6 or 11 floors) and why the columns then would be destroyed is not clarified (KE was suddenly much less and did not impact the columns = the SE). NIST does not consider that misalignment of the two colliding parts means something completely different - unsymmetric local failures of the two parts that will cause transverse movement ... and eventually collapse arrest.
If I come across as a spoilt brat in your mind I recommend that you consult a brain surgeon. Goes for many other participants on this thread.
This is a forum for critical thinking in a lively and friendly way but seems to attract many people with serious brain damages .
