Physical Impact Model Video

And now for a video that is completely different.

If anything I find it odd that no one has done something like this. No one else seems to be demanding to know the tons of steel and tons of concrete on every floor.

The NIST tells us the building oscillated for 4 minutes. How do you compute how much kinetic energy shook the entire building versus how much did structural damage at the point of impact? Isn't that necessary to do an accurate computer model?

Some people at Purdue made this simulation:

I sent them this email about it:

Greetings,

Congratulations on a great looking simulation.

Since some of the kinetic energy caused the entire building to shake and some did damage at the impact zone I was wondering how it was determined how much did what?

In six years I have not heard how much steel and concrete were on each level of the buildings so I am wondering how that information can be obtained.

You see I made my own video but the simulation is based on a physical model. I am having trouble understanding how this incident can be analyzed without the distribution of steel and concrete being taken into account. How many tons of steel were on the impact floors of the south tower to weaken in 56 minutes? I haven't heard that in 6 years.

I got this respone from Chris Hoffmann:

Thanks for your interest.
Please contact Professor Sozen regarding the building particulars.
Best wishes, Chris Hoffmann

I emailed Professor Sozen the same day but I have gotten no response so far.
