But your demand for evidence that the real elements and dimensions were not used in the modelling is interesting. Many people have been demanding that information from NIST for years. And isn't it strange that the very information you demand in order to satisfy your mind is exactly the same as is being sought by others.
Curious if this is accurate:
Either it had shear studs or it didn't. And NIST was being paid to find and report the facts, not play games with: "Studs were not indicated on the design drawings for many of the core girders." vs. "...for the girders." Or is Griffin distorting the truth? Seems unlikely.
