ART LOSS, DAMAGE, AND REPERCUSSIONS
Proceedings of an IFAR Symposium on February 28, 2002
The Artist Residency Program in the Twin Towers
by Moukhtar Kocache
www.ifar.org...
The program was initiated four years ago and provided emerging artists with studio space on the 91st and 92nd floors of the North Tower. Artists worked in painting, sculpture, new media, photography, and art installation and were selected by a jury for residencies that lasted six months. At the end of each six-month period, the studios were opened to the public. Thousands of people came to the Open Studios each year. The LMCC also organized public performances in the large plaza of the Trade Center for thousands of audience members. . . a venue often noted as one of the city's most democratic public spaces.

You
If we simply demanded that they replicate it, with real models, and if they refuse, or cannot replicate it, e
Well, good thing there are multiple photos, video of the collapsing building from different angles, audio, seismic evidence, documentation of the debris, and structural steel of the towers in memorials around the world.
And the reports and accounts that WTC 7 was failing and predicted to collapse.

Yes indeed and we witnessed this:

See you cannot articulate a proper response.
Why would i? You gone and done this already:
the the core columns would have simultaneous pulled down the outer vertical columns (the vertical columns holding up the floor opposite of the core columns, and were part of the towers cores) via the floor trusses.

Except when the upper potion of the building above the Jet impact fell into the building below it broke floor connections. The core failing fist does not explain proven floor connections failures.
Failure of Welded Floor Truss Connections from the Exterior Wall during Collapse of the World Trade Center Towers
app.aws.org...
Analysis of the connections supporting the composite floor system of the WTC towers showed that at and below the im- pact floors, the greater majority (above 90%) of the floor truss connections were either bent downward or completely re- moved from the exterior column. This was probably related to the overloading of the floors below the impact region after col- lapse initiation. Depending upon weld joint geometry, detachment of the main load-bearing seats was a result of either fracture in the heat affected zone of the base material (standoff plate detached from spandrel) or through the weld metal (seat angle detached from standoff plate). Failure in both cases was assumed to be a result of a shear mechanism as a result of overloading from floors above impacting those below. There did not appear to be a significant change in distribution of failure modes of the floor truss connections when comparing those connections inside vs. outside of the impact region or those ex- posed to pre-collapse fires and those that were not.
The below is supported by the video, audio, seismic evidence.
The destruction of the Twin Towers has been called "the most infamous paradigm" of progressive collapse.[6] They began with the local failure of a few structural components and progressed to encompass the whole of the structure.[22] Such collapses are characterized by "the separation of structural components (including non-load bearing elements), the release of gravitational energy, and the occurrence of impact forces." The vertical impact force supplies the propagating action, the principal forces are parallel, and the primary load transfer is serial.[23] The key element in the structure that failed was constituted by the combined "vertical load-bearing members of one entire storey." Excepting the top floors of the building, which would not have released sufficient gravitational energy to bring about a total collapse, the collapses could have begun with the failure of any story.[24]
Under these conditions, the towers collapsed symmetrically and more or less straight down, though there was some tilting of the tops of the towers and a significant amount of fallout to the sides. In both cases, the section of the building that had been damaged by the airplanes failed, which allowed the floors above the impact zone to fall onto the undamaged structure below. As the collapse progressed, dust and debris could be seen shooting out of the windows several floors below the advancing destruction, caused by the sudden rush of air from the upper levels.
During each collapse, large portions of the perimeter columns and possibly the cores were left without any lateral support, causing them to fall laterally towards the outside, pushed by the increasing pile of rubble. The result was that the walls peeled off and separated away from the buildings by a large distance (about 500 feet in some cases), hitting other neighboring buildings, and starting fires that would later lead to the collapse of Building 7. Some connections broke as the bolts snapped, leaving many panels randomly scattered.[25] The first fragments of the outer walls of the collapsed North Tower struck the ground 11 seconds after the collapse started, and parts of the South Tower after 9 seconds. The lower portions of both buildings' cores (60 stories of WTC 1 and 40 stories of WTC 2) remained standing for up to 25 seconds after the start of the initial collapse before they too collapsed.[13]
Collapse initiation
After the planes struck the buildings, but before the buildings collapsed, the cores of both towers consisted of three distinct sections. Above and below the impact floors, the cores consisted of what were essentially two rigid boxes; the steel in these sections was undamaged and had undergone no significant heating. The section between them, however, had sustained significant damage and, though they were not hot enough to melt it, the fires were weakening the structural steel.
As a result, the core columns were slowly being crushed, sustaining plastic and creep deformation from the weight of floors above. As the top section tried to move downward, however, the hat truss redistributed the load to the perimeter columns. Meanwhile, the perimeter columns and floors were also being weakened by the heat of the fires, and as the floors began to sag they pulled the exterior walls inwards. "The ensuing loss in vertical load-carrying capacity was confined to a few storeys but extended over the entire cross section of each tower."[26] In the case of 2 WTC, the eastern face finally buckled, transferring its loads back to the failing core through the hat truss and initiating the collapse. Later, the south wall of 1 WTC buckled in the same way, and with similar consequences.[27]

You have an explanation for the type of floor connection failures?

Here is more evidence that your claims of the core columns remained standing is false. This photo clearly shows there are two holes where the core columns where. There is still a littleof the outer walls still standing once all the dust settled.
The photos you use as evidence of the core columns standing is of the outer walls.
3WHAT ABOUT THE ALMOST FREE-FALL COLLAPSE OF THE TWIN TOWERS? The key is the “almost” modifier. If I told you I was making almost $100,000 and you found out I was making only $67,000, you’d say I was exaggerating. So stop exaggerating the collapse speed of the WTC Towers! The 80,000 tons of structural steel slowed down the collapses of the Twin Towers to about ⅔ (two-thirds) of free-fall.3 And the core collapsed at about 40% of free-fall speed, coming down last.4 According to Richard Gage: “To bring a building symmetrically down, what we have to do is remove the core columns.” But on 9/11 the stronger core columns came down last, which violates this supposed most fundamental rule of controlled demolition.

The Dumbing Down of Architects and Engineers for 9/11 Truth
From video evidence, significant portions of the cores of both buildings (roughly 60 stories of WTC 1 and 40 stories of WTC 2) are known to have stood 15 to 25 seconds after collapse initiation before they, too, began to collapse. Neither the duration of the seismic records nor video evidence (due to obstruction of view caused by debris clouds) are reliable indicators of the total time it took for each building to collapse completely.

LMCC World Views Short Term Project, North Face of 1 World Trade (Floors 89-95)
March 29, 2001
www.travelhome.org...
The name of our collaboration, E-TEAM, is generic. To illuminate it on the North face of Tower 1, World Trade Center, we would use the windows between the 89th and 95th floors like elements in an LCD. It would require 279 darkened and 127 lit windows, and the help of those respective offices. We contacted 14 businesses and provided them with floor plans detailing which blinds to open and close. The support we received from the offices and their employees was integral to illuminating our name.

In your fantasy of CD for the twin towers. If the core fell last. The floor connections were bent downward, or sheared down by a downward force.
Exactly how in you CD fantasy did the supposed charges interact with the twin towers. How many charges, doing what, and where.
After you ignore the twin towers did not fall through the path of greatest resistance.

So is this is how you resolve 9/11? Projecting your perversion of physics just so you can feel comfortable in the official story?
You can ignore the source of the iron micro spheres and all the other facts that challenge the official story. You can lie and twist words all you want, just don't expect me to take you seriously.

911 was fairly well resolved when the Commission noted 60+ times that they found no evidence to support that many elements of the official story.
I never thought I would see the day, but the Covid Hoax is a bigger hoax than 911

I'm totally surprised you didn't show hundreds of old worn out pictures in response.
9/11 is not going to be resolved by your falsehoods and truth movement lies.
Is it false iron micro spheres can be made by other sources other than thermite?

The core was laid bare. No evidence of pyrotechnics cutting columns.
