A professional job would have used explosives (thermite) that completely pulvarized the concrete structures of the building (like WTC). It's obvious the Chinese used explosives only on the lower floors. I'm still evaluating it as to why, but it most likely was due to cost. How does one deal with the intact collapsed structures? Wrecking ball? I don' know.
When a natural disaster strikes like an earthquake, tidal wave, or sink hole, this is how a building collapses. Fire has never in the history of high rises brought down a building EXCEPT of course for those three buildings in NYC. An airplane cannot penetrate the massive wrought iron columns of a high rise building. It's analogous of being paper being cut by scissors.
Thanks. This is true. Do you know the ASTM. I've been out of metallurgy and structural steel for over 30 years now. I recall ASTM A36, but that's about it.
Anyone notice that their controlled demos demonstrate that 9/11 buildings should have toppled over? 9/11 was an inside job.

Cold rolled steel not wrought iron

No problem. Yea most likely a36. Could be the pricier stuff like a572 a992, same idea though
