The First Tri-Center User Workshop on Application of Loss Estimation Methodologies for Transportation Systems was held in Los Angeles from June 24-25, 2003. Hosted by the three earthquake centers (MCEER, PEER, and MAE), the workshop served as a forum to discuss implementation practices, procedures and needs in the field of loss estimation for transportation systems, and to identify future directions for research/user collaboration. The fifty-plus attendees included representatives from state and federal transportation agencies, consulting engineers, and researchers.
The workshop was organized by a tri-center steering committee that included representatives from all three Centers (Ron Eguchi and Stuart Werner, MCEER; Clifford Roblee and Keith Porter, PEER and Reginald DesRoches, MAE). Ian Buckle served as the workshop chair.
The workshop began with representatives from the three Centers presenting current research activities on loss estimation for highway systems. Stuart Werner discussed MCEER’s seismic risk analysis (SRA) procedures using REDARS. Greg Deierlein discussed issues related to performance based earthquake engineering and loss estimation perspectives at PEER, and Reginald DesRoches and T. John Kim discussed MAE’s work in loss estimation and fragility modeling, multi-state SRA applications and visualization issues.
A user panel comprised of Jody Bywater, Washington State DOT, Steven Leung, Caltrans, District 7, Lucero Mesa, South Carolina DOT, Jerry Thompson, Indiana DOT and Bojidar Yanev, New York City DOT, provided feedback to the Center researchers. This was followed by an open discussion on implementation practices, procedures and needs. Two breakout sessions, Damage and Performance Measures for Analysis of Highway Networks and Components, and Data Availability and Analysis Methods for Bridges and Highway Networks provided attendees with an opportunity to discuss specific issues in greater detail.
A jointly funded project to follow up on research needs identified by the workshop is being discussed.
