not at all.....why are the floors above moving......there is NO support resting on floors as in stick frames.....the floors are attached to the continuous vertical support...you have NO evidence the floors nor the continuous load bearing vertical support failed from THESE fires present and neither does any one else......focusing on the reaction instead of the cause gets ya no where.....You're missing the point Bob, the foot represents the dynamic loads of all the floors from above.
well, that's not entirely true....you can fool the unskilled, but only till they learn....then ya can't fool them no more.
one entity was scientifically charged by Congress to determine how and why these three buildings fell on 9-11...and they did not find ANY steel that failed from these fires present to ALLOW collapse to occur.....x3.
look at any video of the collapses......in normal conditions. when does the dust and debris appear????
after there is contact made to make the dust and debris......cept on 9-11
WHY, and how is it possible we see explosive symmetrical discharge of dust and debris AS SOON as there is movement within the towers????
...BEFORE it has any time to make the dust and debris?????
and where does all that pressure come from?????....there is NO containment on the impact floor that is needed to pressurize the air to make it eject as it does....specially with that HUGE hole.
try this at home.......take a 4'x8' sheet of plywood, hold it over your head and throw it so it lands flat......WHEN does he air come rushing out from beneath with velocity?????... as you throw it, or just before it hits the ground......
we see an asymmetrically loaded top section with nothing structurally wrong below the impact floors..
I made a comment about a 4 legged stool up top....attach the legs to a solid surface and knock out a leg.....load for the stool is redistributed and you are still sitting there with 25% of your load bearing capacity removed......NIST scientific investigation found 14.5% asymmetrical damage on the lightest parts of the towers with NOTHING wrong below the initial damage.....
the upper section is the stool.....the bottom is the floor it's attached to.....
how does what we see occur???...then tell me why there is NO supporting evidence anywhere of the 240 remaining fireproofed vertical support failed from these fires present to allow what we see to occur..
