11 сентября 2001It should be noted that it is inconceivable that these experts did not know that it was false. Where is the steel? Since the trusses are incapable of resisting the wind loading, we know that the «official» explanation of the WTC collapse is false. If the floor joists (supports) were not the claimed trusses, then what were they? They had to be strong enough to support the floor slab and stiff enough to resist the wind loading. In fact, they had to be large steel beams. This is not to say that trusses were not used at all in the construction, but just that (contrary to the «official» line) the main floor joists were steel beams and not trusses. The above argument using wind loading is certainly enough to tell one that trusses were not really used as the floor joists, but there are also other ways to determine this. Another approach is adopted in this section. We will: • Calculate the weight of steel theoretically used in the construction of one of the towers assuming that the floor joists were trusses. • Compare the result of this calculation to the 96,000 tons of steel known to have been used in the construction of each of the towers. • Note that the calculated weight of steel is only 67 percent of the required 96,000 tons. • Conclude that the 32,000 tons of steel unaccounted for, is due to the fact the the floor joists were actually weighty steel beams and not flimsy trusses (and thus that the official story is a lie spun to explain away what were obviously demolitions). • Calculate a rough cross-sectional area for the steel beams that did serve as floor joists ...» |
