The movie of the 1 hour and 45 minute lecture given at the Institution of
Structural Engineers in London in 2012 has never been completed,  .....


..... however, when I received invitations to do two keynote addresses - one in DELHI, INDIA, and the other in KARACHI, PAKISTAN in December of that same year, I created a 35 minute excerpt from the London talk as a video to electronically transmit to both India and Pakistan. 

Except for the Title images, both videos here linked below are identical.

As the invitations to give keynote addresses in Delhi and Karachi were received too late for me to fly to either location, and also because the scheduled talks were only 4 days apart, I prepared this video here with two different title slides so they could be presented while I was online, but half way around the world away.

CLICK HERE for the one shown in DELHI at the Terramela Conference.  The talk was renamed Katcha is Pucca and Pucca is Katcha.

CLICK HERE to see the one shown in KARACHI at the 6th Institute of Engineers Pakistan Convention.  This talk was renamed  Traditional is Modern: Traditional Architecture in Seismic Areas.

This excerpt from the London plenary talk describes the traditional earthquake-resistant construction in India, Pakistan Turkey and Portugal.

These movies were transmitted in advance and shown first (and lucky for that as lectures live online would have failed, as difficulties with the Q & A on SKYPE proved very well. However the Question and Answer session for each lecture done live over SKYPE ultimately did work. 

This whole experience of doing lectures by remote was an interesting precursor to the experiences of teaching and lecturing during the Sheltering-In-Place during the Coronavirus Pandemic in 2020.

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 this excerpt 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 may be done some time in the future, but these topics have been covered in my other lectures on this website.

BOTH of the two videos linked above are identical except for the Title Images which were done individually for each presentation.  The top video screen -hosted on WWW.YOUTUBE.COM - is of the version shown in NEW DELHI, INDIA and the bottom video screen - hosted on WWW.VIMEO.COM - is of the version shown in KARACHI, PAKISTAN,

By posting both here, I can give you the choice of watching it on YouTube, or Vimeo - which ever works best for you.
