Wow. Will wonders never cease...
The rude, arrogant naval architect actually deigns to reply to a couple of points.
Well, you say that 13 floors (#98-110) abt 4 m apart in a 53 m high assembly of floors drop and hit one floor, #97.
But floor #110 is 53 m away from floor #97! The only floor that floor #110 can contact is floor#109, but for that to happen you have to remove all columns between floors #109-110.
blah, blah
.
I never said anything of the sort. I laid out clearly & correctly how the forces from the weight of floors 99 thru 110 are transmitted to floor 98: THRU THE COLUMNS to which all those floors are tied.
Nice to calibrate your reading comprehension.
So, let's agree that it is an assembly of floors (#98-110), part C, that is alleged to contact floor #97 that happens to be part of another assembly of floors (#1-97), part A, i.e. part C contacts part A (as suggested by Bazant).
.
WRONG. Is this an example of your high-falutin' "damage analysis"?
It is NOT "an assembly of floors" that contacts another "assembly of floors".
Individual pieces of the upper assembly contact individual pieces of the lower assembly.
Bazant suggests further that part C is rigid (uniform density, it will not deform, it is indestructible at this time) but it is nonsense. And therefore Bazant's model is nonsense.
.
WRONG.
You have been told AT LEAST 20 times that "rigid body" does NOT mean "indestructible". And yet you obliviously yammer on.
Now, you suggest that an assembly of floors, upper part C, is capable to one-way crush down lower part A, floor by floor, i.e. 97 impacts take place.
.
As I said before - and you have once again demonstrated - you couldn't pour piss out of a boot if I wrote the instructions for you on the heel.
And you certainly cannot accurately interpret anything that I have laid out in simple, concise terms that any freshman engineering student could understand.
So, please listen carefully. I INSIST that you not attempt to interpret for anyone else ANYTHING that I've said. Because you cannot get the simplest statement right.
With reference to me, you have my permission to say that there is another experienced mechanical engineer that thinks that you are wrong at just about every single assertion you've made. And if anyone would like to read for themselves what I believe, they should ask me directly.
Of course, if you'd like to be completely accurate, you should say that ALL competent engineers think that you are full of baloney. But I'm sure that you'll take comfort that bill smith thinks you're a genius...

Yes, your opinion is quite clear.
Your opinion is that:
"There is no difference between static & dynamic loading."
"Buildings are just ships without all that moisture around."
"ALL the structural engineers in the world are about to be eclipsed in their knowledge of collapse dynamics by some arrogant amateur who happens to be a naval architect."
"You have anything whatsoever to tell Zdenek Bazant about structural mechanics."
ALL of the above are laughable.
Your suggestion is impossible! Actually a ridiculous suggestion.
.
Let the skipping record begin in 3 ... 2 ... 1 ...
Because at impact C on A, local failures will occur in both C and A. The weak elements or weak connections in both C and A adjacent to the impact interface fail first. Energy is absorbed as local failures. A jolt (decelaration - unit m/s²) of C should be observed. Then damaged elements will displace and contact other elements. Friction develops. More energy is now absorbed as friction. Etc, etc. And after a while of more local failures/friction the destruction is arrested. Happens every time you drop a part C of a structure A on the rest of A. It should take less than ONE second in the WTC 1 case.
.
ahhhhhh, THERE it is.
SOMEBODY KICK THE JUKEBOX, PLEASE...!!
This is the reason Why a one-way Crush down is not possible = topic = post #1.
.
Because you say this again, and again, and again?? With ZERO engineering analysis to support your nonsense.
Why don't you threaten to hold your breath until you turn blue. Perhaps that will get someone to notice you.
Anyone suggesting that part C structure can one-way crush down part A structure is complicit to mass murder! Let's expand the thread to include that suggestion.
.
SURE THING, Anders.
Let's expand the conversation to this pathetic accusation.
Your idiocy has now come full circle and constitutes a complete whole of stoopid.
You are incompetent. You can not understand the simplest of engineering arguments. You refuse to discuss the ones that you KNOW you have misstated.
Real engineers, real scientists, and real non-techies who can simply read (& watch you run from real discussions) KNOW that you are simply, utterly, laughably wrong.
And now, you offer this little pile - that anyone who disagrees with your blatantly wrong crappola is "complicit to mass murder".
Anders, what you have offered here is PRECISELY the same nonsense as "anyone who suggests the earth moves is a heretic." Or "Anyone who suggests that man descended from other animals offends God."
Wrong, Anders.
Anyone who says that a one-way crush down is possible simply has the good sense to listen to the WORLD's foremost experts on the matter.
And to ignore one looney-toons naval claims adjuster who won't even bother to attempt to defend - honestly - his own nonsense.
Sounds to me like the are guilty of "complicity to use their brains, common sense & good judgment".
