NCEER HSRC Holds Second Meeting
The second meeting of NCEER's Highway Seismic Research Council (HSRC) was held October 1 and 2 at the University Inn and Conference Center in Buffalo, New York. Held the day after the Highway Project researchers meeting, it afforded council members an opportunity to comment on ongoing Year 1 projects with the researchers.
NCEER Director George Lee welcomed the HSRC to Buffalo. The Federal Highway Administration's (FHWA) John O'Fallon expressed his enthusiasm for the project and extended the FHWA's confidence that the NCEER researchers and council members will accomplish the difficult goals of the project. Carol Kizis, QUAKELINE® Database Coordinator, provided an overview of NCEER's Information Service. Ian Buckle, NCEER's Deputy Director, then provided an overview of the Highway Project's scope, objectives and end products.
The meeting was organized into a series of technical breakout sessions on the following topics:
- Foundations and Soils
- Design Issues/Details (Concrete/columns/bearings, etc.)
- Seismic Hazard/Ground Motion
- Analysis and Special Issues (Analysis and EPS)
- Performance and Design Criteria
- Analysis and Special Issues (Fragility and Risk Assessment)
Each technical group discussion was moderated by a member of the Highway Project Research Committee, who served as group leader and presented progress in that area to the HSRC members. The HSRC members were encouraged to ask questions of the research team, and to discuss the progress, approach, and other task-related issues.
During lunch on Friday, William Stone, from the National Institute of Standards and Technology, provided an overview of his agency's seismic column research program and proposed research activities.
On Saturday, the HSRC's technical and coordination groups held separate executive sessions to review their findings from the technical discussion groups. Their comments on Year 1 research progress and Year 2 research directions will be summarized in reports to NCEER, and were briefly discussed with the researchers during the meeting's morning session.
After the meeting concluded, a number of HSRC members and researchers participated in a field trip to East Aurora, New York, where a pair of parallel bridges are being rehabilitated by the state. As part of the rehabilitation, the existing steel bearings are being replaced with elastomeric bearings on one bridge and seismic isolation bearings on the other bridge. Professors John Mander and Stuart Chen of the University at Buffalo are conducting "snap-back" lateral load tests on both bridges prior to and after the bearing replacements to determine and compare the change in dynamic behavior of the structures with steel, elastomeric, and seismic isolation bearings. Several tests at different load levels were conducted during the field trip.
The HSRC has 25 members, many of whom are nationally recognized experts in their field. They are divided into two groups - coordination and technical. They are charged with providing advice on the technical aspects of both research contracts and in ensuring coordination with other agencies involved in earthquake hazard mitigation and end-user implementation of the research products that will be developed under the program.
