I'm pretty sure the data about the WTC's factor of safety -- and how strong it was -- was not known to Hamburger when he authored the FEMA report on the WTC collapse. When that interview was probably done. I suggest you check the date. It was probably 2002.
We have learned a lot since then.
It's clear that NIST's own data failed to support the official conspiracy theory about 9/11.
No doubt, it's why NIST buried the demand/capacity ratio data for the WTC deep in its report. You'll never find it unless you know where to look. Mark Roberts obviously never knew about it -- until I told him. But he did not listen. He is a typical knee jerk.
Just like you clowns.
So you're sure Hamburger has changed his mind since then? What if he hasn't? Should I e-mail him and find out?
And I checked the pages you cited. Look again Gaff, the figures are not there.
P 100 starts with: "Figure 4-34 shows the finite element model . . . " This page discusses the buckling of a one-story high exterior column in room temperature vs 700 degrees celcius.
P 233 starts with: "8.2.2 Model Modifications. The validated ANSYS models . . ." This page contains mostly computer graphics and a paragraph about their computer model and modifications thereof.
Neither page says anything about demand capacity ratio of core or perimeter columns.
