Not totally understanding the issue of viscoplasticity, but it would seem to me the entire supporting middle columns of the WTC 1 and 2 would need to reach the temperature required for failure...how does this result in iron-rich microspheres?

1) fires and impact acted alone to cause the collapse....(forgetting building 7)
2) there was a full global failure on the floors in both buildings so the upper block accelerated down all at once onto the lower block allowing a top down collapse in a steel structure.....
3) temperatures were high enough to cause the steel to weaken and become plastic (globally)
even though the impacts were in different parts of the building and one impact only caught a corner section in the case of the South Tower
.forgetting the fact the the further down the structure it progressed the greater the resistance as the lower in the towers one progresses the more substantial the structure became.
key elements to consider here..the cross bracing of the central core
.which would result in resisting the very buckling that is presented by Bazant and Greening
now for the simple people out there still spewing their physics....PATH OF LEAST RESISTANCE.
remeber conservation of energy does always aplly wther the collision is Elastic or Inelastic
so Stop lying to the people.....better yet stop lying to yourselves.
now once again the fire was not global.....it did not affect all areas of the structure globally allowing complete failure of entire floors as Bazant would try to have the World believe.
and to ignore physics just stinks to high heaven and Mister joey Canolli trys to baffle people with BS

260-315°C (500-599°F)
The critical temperature is often considered the temperature at which its yield stress has been reduced to 60% of the room temperature yield stress.[6] In order to determine the fire resistance rating of a steel member, accepted calculations practice can be used,[7] or a fire test can be performed, the critical temperature of which is set by the standard accepted to the Authority Having Jurisdiction, such as a building code. In Japan, this is below 400°C[citation needed]. In China, Europe and North America (e.g., ASTM E-119), this is approximately 1000–1300F[8] (530-810C). The time it takes for the steel element that is being tested to reach the temperature set by the test standard determines the duration of the fire-resistance rating. Heat transfer to the steel can be slowed by the use of fireproofing materials, thus limiting steel temperature.
The tube frame design using steel core and perimeter columns protected with sprayed-on fire resistant material created a relatively lightweight structure that would sway more in response to the wind
I don't know about that, but he would definitely take such a request much more seriously than Obama, Romney, Gingrich, or any of those puppets. If enough of the people requested one, I'm sure he would listen, because he would be there to serve the people rather than corporations and special interests.
If Ron Paul would somehow overcome the bias, MSM, and otherwise to become President, do think there's a chance that he could have a new investigation started?

Just simple facts that you simply cannot understand.
Open air burning temperatures 260-315 °C (500-599 °F)[7]
