As a qualified engineer who works in the field of failure analysis
and prediction I suspect I am far more knowledgeable and
qualified in this field than either you or Professor Jones and I
have read the investigation reports and failure analyses.

The towers collapsed due to the failure of the struts linking
the damaged inner and outer cores. The outer shell failed in
buckling with a resultant progressive collapse , the floors above
the point of failure acting as a gigantic hammer overloading
each floor in turn

The weakness of struts in a fire is well understood by firemen,
those I have spoken to have a saying 'never trust a truss'

As lightweight steel structures they heat up fast and fail
relatively quickly compared with heavier steel joists.

Keith, you're a qualified engineer. Please give your professional
opinion on these excerpts from Jones' paper (be sure to watch the
video links too):



I did so some days ago - clearly you werent listening

If you want a professional analysis it will cost $1500 per
day plus expenses, minimum charge period is one day.

I thought your name was Mike???

Then why do you say, "Keith, you're a qualified engineer" and ask for
his opinion? Man, the 60's were good to you. You are in a discussion
with Keith and surprised when he signs his name "Keith" again.
