Lessons Learned over Time

The two papers in this volume illustrate how the January 17, 1995 Kobe (Hyogo-ken Nanbu) earthquake was a catalyst for rapid change: 1) "Bridge Repairs After the 1995 Kobe (Hyogo-ken Nanbu) Earthquake," by Caltrans Bridge Engineer Mark Yashinsky, surveys the damage to bridges and highway transportation structures and describes how the need to retrofit to an improved seismic standard drove immediate research to determine appropriate criteria and methods for repair and retrofit.2) "The 1995 Kobe (Hyogo-ken Nanbu) Earthquake as a Trigger for Implementing New Seismic Design Technologies in Japan," by structural engineers Peter W. Clark and Ian D. Aiken, with input from Japanese colleagues M. Nakashima, M. Miyazaki, and M. Midorikawa, provides a broad perspective on the implementation of isolation technologies in the wake of the Kobe earthquakeYashinsky, Mark is the author of 'Lessons Learned over Time', published 2000 under ISBN 9780943198972 and ISBN 0943198976.
