PROJECT OVERVIEW

Title:14th U.S.-Japan Workshop on the Improvement of Structural Design and Construction Practices

Project Status: This Workshop was conducted on December 3-5, 2012

Sponsors: Applied Technology Council (ATC) and Japan Structural Consultants Association (JSCA)

PROJECT SUMMARY

The Purpose of the Workshop is to provide a forum for the exchange of ideas and information relating to the improvement of current building design and construction practices in the United States and Japan. The special focus of this Workshop will be on issues relating to the performance of buildings and other structures in severe earthquakes, including the effects of tsunami, and response and recovery.

The Workshop is the 14th in a series started in 1984, and repeated every two-to-three years. Previous workshops have been held in California (San Diego and San Francisco), Hawaii (Honolulu, Kauai, Kona, Kohala Coast, and Maui), Japan (Kobe and Tokyo), and Victoria, British Columbia.

Workshop Participants.  The Workshop Participants included those with a background in building performance and other structures in severe earthquakes, including the effects of tsunami, and response and recovery.

Workshop Program.  The Workshop Program was designed for practicing structural engineers and researchers, and included technical presentations, and working group breakout sessions and discussions. Papers and presentations were as follows:
