Love how Debunkers use WTC5 as evidence when it was on fire and building remained.

You
Love how Debunkers use WTC5 as evidence when it was on fire and building remained.
But there was fire related failures and the collapse of floors in WTC 5.

And why don’t you want to talk about all the smaller floor connections that where bent down and sheared from the vertical columns?
How many pieces underwent the sulfur attack again? Can you put a number to the amount of pieces? Or you talking an isolated case limited to a few pieces?
I can merely go by what they released online. I strongly believe there was many more dump locations with identical steel. The photographs were captured at just one location in Oct 2001.

You mean like stuff that was found in WTC 5
WTC5 other locations. Steel pieces from WTC1 and WTC2 impacted the construction. Connections will certainly come apart from that.
What a twisted-column 4.14 it not failed column. That column may have received shot by an object. It a tiny picture with no good view of the surrounding destruction.
Love how Debunkers use WTC5 as evidence when it was on fire and building remained.
4.18 you can determine the floor girders and joists and trusses are still there did not collapse What a weird position its the debunker claim fire led to a failure of comparable joists, trusses and beams and girders at WTC7 scene?
A partial failure caused by tower debris reaching the building, it not evidence to demonstrate the other collapse are possible..
What are you rambling about?
Do you have any evidence that the collapse of WTC 1 and WTC 2 was initiated by and sustained by detonations.
Considering the vertical columns fell only after the loss of lateral support of the floor system, with no evidence of being cut, I say no.
WTC5 partial floor failures were caused by fire and debris from the towers collapse. You, people, are claiming three-buildings failed entirely to just fire alone

The debris from the WTC site was carted to Fresh Kills landfill on Staten Island for sorting and analysis
Manhattan is an island , in case you don't know, with only limited ways on/off via tunnels and bridges
Explain how procession of dump trucks is going to leave Manhattan without being notices and where they would be going …...

Then should be easy for you to quote the post. Or just more innuendo by you.....

Partially false statement with miss leading innuendo.
WTC 5 report for you to actually quote.

Looks like the roof is intact above the closest floor failures....
Two areas in WTC 5 experienced local collapse under an intact portion of the roof. Although there was debris impact near this area, the symmetrical nature of the collapse strongly suggests that the failures were due to the uncontrolled fires. This is supported by the observation that the columns in this area remained straight and freestanding (see Figure 4-18). This local collapse appeared to have begun at the field connection where beams were connected to shop-fabricated beam stubs and column assemblies as illustrated in Figures 4-19, 4-20, and 4-21.
The structural collapse appeared to be due to a combination of excessive shear loads on bolted connections and unanticipated tensile forces resulting from catenary sagging of the beams. The existence of high shear loads, likely due to collapsing floor loads from above, was evident in many of the column-tree beam stub cantilevers that formed diagonal tension field mechanisms in the cantilever webs and plastic moments at the column, as seen in Figure 4-18.
It is apparent that fire weakened the steel, contributing to the large shear-induced deformations observed in several of the cantilever beams. The shear failures observed at connection ends in several of the beam web samples shown in Figure 4-18 are indicative of the tensile forces that developed. The end bearing resistance of the beam web was found to be less than the double shear strength of the high-strength bolts, based on the analysis presented in Appendix B.
Steel framing connection samples were recovered from floors 6, 7, and 8 of WTC 5 with the aid of the New York Department of Design and Construction (DDC) and are described in Figure 4-22. These samples have not been analyzed and are being preserved for future study. The photographs of connection samples in Figure 4-22 indicate that the deformed structure subjected the bolted shear connection to a large tensile force. At 550 °C (1,022 °F), the ultimate resistance of the three bolts is about 45 kips. The capacity increases to approximately 90 kips at room temperature. Connection failure likely occurred between these bounds.
Tensile catenary action of floor framing members and their connections has been neither a design requirement nor a design consideration for most buildings. Further study of such mechanisms for member failures in fires should be conducted to determine whether current design parameters are adequate for performance under fire loads.

So. You have absolutely no evidence the collapse initiation of WTC 1 and WTC 2 was from detonations, and no evidence the collapse of WTC 1 and WTC 2 were sustained by detonations.
You can't give any evidence fire would go on this to the steel.

You lose again....
Try doing some research first before beclown yourself
Pretty incredible if you think about when these are the first known failures of steel-framed buildings in history.
The Windsor Tower Fire, Madrid
The Damage
The Windsor Tower was completely gutted by the fire on 12 February 2005. A large portion of the floor slabs above the 17th Floor progressively collapsed during the fire when the unprotected steel perimeter columns on the upper levels buckled and collapsed (see Figure 1). It was believed that the massive transfer structure at the 17th Floor level resisted further collapse of the building.
The whole building was beyond repair and had to be demolished. The estimated property loss was �72m before the renovation.
Based on the footages of available media filming, Table 2 summarises the estimated time frame for the structural collapses of the Windsor Tower
East face of the 21st floor collapsed
1:37 South middle section of several floors above the 21st floor gradually collapsed

2:51 Southeast corner of about 18th ~ 20th floors collapsed
3:35 Southmiddlesectionofabout17th~20thfloorscollapsed Fire broke through the Upper Technical Floor
3:48 Fire flame spurted out below the Upper Technical Floor 4:17 DebrisontheUpperTechnicalFloorfelldown
Analysis
The main factors leading to the rapid fire growth and the fire spread to almost all floors included:
the lack of effective fire fighting measures, such as automotive sprinklers
the “open plan” floors with a floor area of 1000m2
the failure of vertical compartmentation measures, in the façade system and the floor openings
It was believed that the multiple floor fire, along with the simultaneous buckling of the unprotected steel perimeter columns at several floors, triggered the collapse of the floor slabs above the 17th floor. The reduced damage below the 17th floor might provide a clue.
