Oops, I know that the code is for building design, and that in order to "comply", the structural docs would have to be released, something that NIST is legally prevented to do due to privacy laws.
And.... building design and collapse modelling are 2 different things, and so maybe if I bluff enough, I might be able to convince my fellow conspiracy minded users of this website. Too bad it won't hold water in the real world though. In the real world, as opposed to Twoofaloon world, I must prove my points, something I can't do....
The ICC Performance Code® for Buildings and Facilities clearly defines the objectives for achieving the intended levels of occupant
safety, property protection and community welfare. The code provides a framework to achieve the defined objectives in terms
of tolerable levels of damage and magnitudes of design events, such as fire and natural hazards.

Now, if you believe this doesn't encompass modeling a building's performance during a fire, then can you suggest one that better fits?

You started a thread claiming that NIST were required to follow the ICC codes used when constructing a building, but you never provided any justification for this other than your own opinion.
Do you have any evidence whatsoever that NIST has any requirement to follow these codes or are you just trying to cast doubt onto the NIST report by speculating wildly?
The National Institute of Standards and Technology (NIST) and the International Code Council (ICC), and their predecessor organizations, have a rich and sustained history of cooperation and partnership that builds on our deep and shared dedication to building safety and fire prevention. Many of you probably know of, or have worked with, my predecessors—Dick Wright, Jack Snell, and Jim Hill. At the request of NIST Director Bill Jeffrey, Jim Hill is now serving as acting deputy director for all of NIST.

Lets not forget of course that NIST has released their SAP2000 model which includes the weights and details of the structure. It seems you are simply trying to poke holes in the "official story" rather than proving any sort of alternate hypothesis.
This appendix gives guidance regarding qualifications and information that should be provided when undertaking computer modeling.
More specifically, the appendix requests that computer program data be submitted as part of the documentation. Also, limitations
and applicability of the model must be included as part of the documentation. Finally, the scenarios used to run the particular
model must be justified.

wtc 7, don't know what happened there. That looks a little funny to me.
BOMA, other representatives of the commercial real estate industry, and many code and safety experts opposed these code changes. BOMA argued that the need for an additional stairway in particular was not demonstrated by NIST and other proponents, and, given current fire statistics, is not well founded. A full cost/benefit analysis necessary to document the societal impact of these sweeping changes was not performed as part of the NIST study, as was repeatedly urged by BOMA and many other groups. This change was also opposed by the ICC technical committees with oversight of egress requirements in the ICC codes. Building construction experts noted during the ICC public hearings that proponents for this change did not demonstrate the need for the stairwell in actually contributing to the safe evacuation of a building - a particular concern in view of comments by the fire service during the hearings.

If you are referring to the close up which then pans outwards.....and thats what i presume, how can that be construed as spreading disinfo....
Or perhaps i am missing your point...
Care to elaborate...??

No. My opinion is that NIST should have no governance over codes that they fail to follow themselves.
Can you show me where NIST included their limitations of their model as part of their report? I must have missed that part.
BTW, I never claimed to be an expert on these codes. Hence why I keep asking if there is another code that would be more suitable to compare with. But, all I have recieved in return is being called "stupid".

no, the original video, that i have seen, distinctly shows small explosions (ejections) out of the windows below the debris as the building is collapsing. Because these explosions have been removed, this edited video, is not congruent with all of the other un-doctored recordings of this collapse. If you extract the video from youtube and inspect it with any high quality video program, the loss of pixels due to editing, and the impossible physics of the "smoke" in the area i'm describing is clearly visible.
Although i doubt it, this could be attributed to poor rendering quality, but the explosions clearly visible in the original video have been severely dampened . . .
i'm looking for the original video, when i find it, i will post it ASAP
edited: "video" found
this is not the exact video i was looking for, but it gets the job done . . .

Those are massive explosions which are preceding the 'collapse' by at least 6-10 floors. You can also clearly see the huge exterior 4-ton wall sections being blasted up and out and down onto the neighboring buildings; including Winter Garden and WFC3.

You have not shown that NIST is required to adhere to these codes in any manner.
In contrast, structural design practice in civil engineering is characterized by: (1) its governance by codes of practice, which are an integral part of the system of federal, state and local laws in the United States; (2) its concern with demands placed on a facility by the natural environment as well as by facility operation; (3) its reliance on computation and analysis ragher than on product testing; and (4) cost factors that determine the success of the civil project. Traditionally there have been three Model Codes in the United States: Basic, Standard and Uniform. Beginning in the year 2000, there is only one; the International Building Code (IBC). Model codes, when adopted by governing bodies, become part of law. Model codes, in turn, are derived from nationally recognized standards and specifications that are developed through the voluntary consensus standard approval process in the US. These standards include ASCE Standard 7.98 (Minimum, 2000) on minimum design loads, ASCE Standard 16-95 (Standard, 1996) on engineered wood construction, the AISC LRFD Specification for Steel Construction (Load, 1993), and similar, documents. This comprehensive system of building codes and standards and its linkages with statutes governing public safety govern structural engineering practice for civil construction in a way not found in most other engineering applications.
but lets not forget NIST is not constructing a building, they are attempting to model the processes involved in an already constructed building.
Very few people here have any experience with building code, do you really expect to get a good answer here or are you just trying to discredit NIST?

Federal Agencies
The GR Federal Agencies Team was established to guide ICC activities with Executive Branch agencies of the federal government. The GR staff has and continues to monitor the activities of and interact with federal agencies. The ICC is strengthening its interaction with key decision-making federal agencies in order to secure recognition and use of ICC codes and standards and services as well as their increased participation with the ICC.

Why and how would explosions possibly push external sections upwards? Can you suggest some mechanism or reason? In fact why would they even push the columns outwards in such a violent manner? You are aware that demolition explosives cut columns, rather than displacing them like this?

After a building collapses it looks like this...
see the concrete still intact ??
Of course, the above photos were caused by earthquakes...
