This 35 minute excerpt from a
February 2012 Lectures at the History Study Group of the Institution of Structural Engineers
in London and The College of Engineering at Oxford University
was made into a video presentation so that it could be shown in
December 2012 at the New Delhi, India TerraMela Conference
and at the Institution of Engineers, Pakistan Conference
in Karachi, Pakistan, 4 days apart. This video lecture was used
because both invitations came too late to travel to either site.
The Question and Answer session for each lecture was done live over
The original Institution of
Structural Engineers lecture was 1 hour and 45 minutes in
length, and the original Oxford University lecture was 1 hour
in length. The material in those lectures not in these
excerpts covers the 2010 Haiti Earthquake, and also an extensive
discussion of the evolution of modern RC moment frame construction.
A video of these parts of the talk is under preparation and will be
posted when it is completed.
BOTH of the two videos below are
identical except for the Title Images which were done individually
for each presentation. The top video screen - hosted on
WWW.VIMEO.COM - is of the version
shown in KARACHI, PAKISTAN, and the bottom video screen - hosted on
WWW.YOUTUBE.COM - is of the
version shown in NEW DELHI, INDIA
By posting both here, I can give
you the choice of watching it on YouTube, or Vimeo - which ever
works best for you.
In VIMEO screen
