The NIST Final Draft on the collapse of World Trade Center building 7 has many flaws, including blatant fraud. In their June 2004 report (and in the actual shop drawings*), NIST referred to the use of shear studs in World Trade Center 7. Shear studs are used to keep steel floor beams and girders in place; they impart stability and strength to buildings. But in their August 2008 final report, NIST re-worded their comments on shear studs to make it appear that none were used on the floor girders. Why would they do this? To know the answer, you need to understand NIST’s collapse theory. This is how it goes: 1. The key girder between column 79 and the exterior wall fails at floor 13. 2. Its failure causes the collapse of floors 13 through 6. 3. Column 79, now unsupported laterally by these floors, buckles and brings down the entire building. This scenario is easier to posit if the key girder isn’t being held firmly with shear studs. Thus, in the August 2008 report, NIST did what it had to do to make it more reasonable that the girder would fail: It magically omitted the shear studs. --Chris Sarns & Judy Shelton.
