Workshop Review


U.S.-Italian Workshop on
Seismic Evaluation and Retrofit

by Daniel Abrams

The U.S.-Italian Workshop on Seismic Evaluation and Retofit, jointly sponsored by NCEER and the Italian Gruppo Nazionale per la Difesa dai Terremoti (National Group for the Defense Against Earthquakes - GNDT), was held on December 12-13, 1996 at Columbia University. The workshop reciprocated a previous NCEER-GNDT workshop on the same topic held at the University of Pavia in June of 1994. Both workshops were organized under the auspices of a Memorandum of Understanding between the GNDT and NCEER.

Chairs of the workshop were Dan Abrams of the University of Illinois and G. Michele Calvi of the University of Pavia. Klaus Jacob and Christian Meyer of Columbia University served as local hosts. Invited U.S. participants included Sashi Kunnath, Andrei Reinhorn, Mark Aschheim, Khaled Mosalam and Raimondo Betti. Italian participants were Ezio Faccioli, Luigi Gambarotta, Sergio Lagomarsino, Mauro Dolce, Edoardo Cosenza, and Paolo Pinto.

The focus of the meeting was on seismic evaluation and rehabilitation of buildings and bridges, with an emphasis towards basic issues for conducting research and implementing research results. Invited papers presented state-of-the-art summaries on:

  1. Mitigating Earthquake Hazards
  2. Estimating Ground Motions for Assessment of Existing Structures
  3. Improvements in Seismic Evaluation through Advanced Computational Methods
  4. Vulnerability Evaluation and Damage Scenarios
  5. Seismic Evaluation and Rehabilitation of Concrete and Masonry Buildings
  6. Seismic Evaluation and Rehabilitation of Transportation Networks

Discussions at the bilateral workshop helped identify common technical problems and solutions, research gaps and needs, implementation issues, future directions of seismic codes, and ideas for technology transfer for improving future collaborative research. Based on these discussions, a set of resolutions were formulated, and grouped with respect to ground motion modeling, computational modeling of seismic response, evaluation and retrofit research, vulnerability studies and future actions. These resolutions will be published along with the technical papers as an NCEER report in 1997.
