This image-filled presentation will illustrate the link between indigenous and traditional seismic retrofit techniques from different parts of the world and explore how they relate to the techniques used in historic buildings today.  Stephen J. Kelley, who has extensive experience diagnosing, communicating, and implementing treatments for particularly vexing structures outside North America, will utilize examples from projects in Europe, Asia, and the Americas. He will also discuss in detail regions and heritage structures affected by disaster including earthquakes, a topic that many engineers find hard to navigate. This presentation is for everyone and not just for the earthquake professionals.

Learning Objectives:

• Review the various types of earthquakes.
• Analyze how different building materials and systems behave in an earthquake.
• Explore the development of traditional seismic retrofit techniques in earthquake prone regions of the world.
• Discuss how traditional retrofit techniques can inform the retrofits that we use today.
