Isthis because the perimeter wall was not actually meant to be a load bearing wall as such, but a feature designed to give the WTC its required rigidity (against wind loading)? In the left photo note the yellow and red lines in the concrete. In the right photo note the three parallel light-colored lines (about 4 inches wide) in the concrete. One also wonders why the pile of steel in the foreground was hoisted up the building, unless it was to be incorporated in the structure. An answer to this question may be provided by the following photo.
Between the workers cutting up a couple of WTC core columns, is a column with concrete still attached to the beams that are welded/bolted to it. These U-shaped beams look suspiciously like the lengths of steel in the foreground of the picture of the trussing. Is it possible that floor slab was some eight inches thick and laced with significant steel beams? Was the slab poured in situ and not prefabricated as some claim? Was the temporary flooring only necessary till the concrete in the floor slabs had set? And where does the following piece fit in the whole affair?
Conclusion
• Impacts of the magnitude of those that occurred on September 11 were considered by the designers of the twin towers and the towers were designed to survive them.
• The possibility of a jet-fuel fires the size of those that occurred on September 11 were considered by the designers of the twin towers and the towers were designed to survive them.
• In order to explain why the towers collapsed, where other steel framed buildings would have survived, the WTC conspirators invented the «truss theory».
• The «truss theory» is seriously flawed. It cannot explain how the perimeter wall transmits wind loading to the central core.
• The «truss theory», if accepted, leads to a 33 percent underestimate of the amount of steel in the towers. That is, the «truss theory» does not account for the whereabouts of 32,000 tons of steel (of 96,000 tons) used in the construction of each of the towers.
• The «truss theory» is a lie that has been spun to convince a gullible public, that what appeared to be the controlled demolitions of three of the World Trade Center buildings, were actually natural consequents of the aircraft strikes and not controlled demolitions at all.
• There are photos showing large steel girders positioned where the «official» line states that only (double) trusses should be.
