Katcha is Pucca & Pucca is Katcha
How one of the oldest known construction typologies
may be key to preventing pancake collapse of
modern reinforced concrete buildings in earthquakes. 

A lecture
by
Randolph Langenbach
at the World Bank on December 6, 2011

This slide presentation explores a comparison between traditional forms of construction and the most common contemporary construction type now used throughout much of the world reinforced concrete with infill masonry. The session will discuss how one of the traditional construction typologies could form the basis for possible collapse-prevention improvements to standard reinforced concrete construction in earthquake areas, such as Sikkim, India, Van, Turkey, as well as earlier in Haiti and other parts of the world where many modern buildings have suffered pancake collapse.
