Sorry Doc, missed that part about the scattered fires.
We have a building that is hit by the twin towers, it got a hole in it, there is fire, yes where smoke is is fire, but a small fire can cause a lot of smoke. now let's go to the situation of raging fires, whatever caused it is not relevant, a burning part from the WTC or an exploded tank.
Now 7 hours later it is evacuated, all structures are still intact (of course there is that gaping hole) and when people say "did you hear that, building is coming down, it is about to blow up" etc. it does come down, they were able to determine exactly the moment. Now as a discontinous function a shockwave goes through the whole building even before it starts moving with 9.1 m/s^2. if this really is caused by fire and a few columns that are gone then the whole science of CDs need to be revisited.
A cd is really a high-skilled job in which you
- exactly study the building
- need to determine where to place a minimal amount of charges
- cut also some columns on higher levels or place charges there
- connect a computer system to time it very precisely, a random timing will lead to a failed CD.
If the requirements for a CD are met then it will be a good and complete collapse. How could fire lead to the required conditions ? We will seen soon, but I'm afraid it will again be a half baked farce.
