35 minute lecture on:
The traditional earthquake-resistant construction in India, Pakistan Turkey and Portugal.

This is an excerpt from an hour and forty-five minute lecture given in February 2012 at the UK Institution of Structural Engineers in London


Randolph Langenbach, 2012

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 SKYPE.

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 above, to watch in full HD, click on "HD" on the lower right side of the video screen.  In the event that the video streaming is frequently interrupted, turn the HD off.

Be sure to first select this by clicking on "change quality" (the gear icon) as illustrated below.

It is then recommended that you click the
FULL SCREEN button on the lower right as shown below.
