Funneling Trapped Debris: ROOSD concepts
Attributes of a Rubble Driven Collapse
Models of Inelastic Accretion
It could be called the "ROOSD principle" or the "ROOSD paradox", which is...
If the towers were constructed 1000 stories tall and the same 12 story section as in the case of WTC1 starts to fall, it could destroy the whole building.
According to ROOSD, if the tower was 10,000 stories tall and of the same design, the top 12 stories could "crush" the 9,988 stories below.
Also, amazingly, bulky debris within the perimeter would stay confined to the tube while perimeter sheets opened outward and broke off at the base like petals of a tulip.
>>>>>>>>>>>>>>
The ROOSD paradox is that the height of the building does not matter. This is why 12 stories of WTC1 could "crush" the lower 98. The same 12 stories could have "crushed" 198 stories had the earth not stopped the process.
There is no paradox, obviously, but it is for those who see the buildings as "blocks" or a great buckling accordian. It also shows how easy it is for a demo team to use the ROOSD process.
They really do not care how high they are in the building, the higher the better.
Fundamental conditions for ROOSD
The most fundamental number relation for ROOSD is that...
Floor connection strength...... is much, much less than........ column buckling strength.
This is why ROOSD erosion can strip wall and core. They never compete because ROOSD stripping never threatens the column strength.
