Yes. NIST itself is peer reviewed. So are Dr. Bazant's numerous papers on the subject, so is Dr. Seffen's, so are the many other papers including computer simulations from China and South Korea.
There is in fact such an excess of energy available that hardly anyone has bothered to come up with a precise theory of collapse. Even the most conservative models predict the total collapse of the structures. There's little point going any further, unless you're a Truther clutching at straws, but that's not science at all.
Yes I believe the NIST theory goes somehing like 'The top and lightest one-tenth of the building overcame all the strain energy that could be supplied by the 47 massive upstanding core columns and their perfectly intact integration with all the other vertical and horizontal components in the lower nine-tenths of the building that was anchored 70 feet deep in the ground.'
This one-tenth made contact after a short drop with the intact lower nine-tenths of the building creating a layer of rubble at the interface.
Essentially this layer of rubble created more rubble which grew and grew like Pinnocchio's nose, taking only from the lower part and leaving the upper one-tenth 100% intact- a bit like Robin Hood in fact if you stretch the analogy a little.
Down and down went the upper one-tenth causing the rubble layer to grow and grow until the building was aaall gone. Then the upper one-tenth was rushed up
.....and they all lived happily ever after.
If it sounds like a fairy tale that's because it is a fairy tale.
