FOURTH NATIONAL WORKSHOP ON BRIDGE RESEARCH IN PROGRESS:
 
RESEARCH ABSTRACT
 
Title:
Longevity and Reliability of Sliding Isolation Systems
Author(s) and Affiliation(s):
Michael C. Constantinou, Panos Tsopelas and Amarnath Kasalanati Department of Civil Engineering State University of New York at Buffalo, Buffalo, NY
Principal Investigator:
Michael C. Constantinou
Sponsor(s):
Federal Highway Administration and National Center for Earthquake Engineering Research
Research Start Date:
October 1, 1992
Expected Completion Date:
June 30, 1996
Research Objectives:
The objectives of this study are to collect data and generate new experimental data on sliding bearings with emphasis on factors affecting their long-term service life in relation to applications of bridge seismic isolation, and to establish bounds on the frictional properties of sliding bearings for use in the analysis and design of seismically isolated bridges.
Expected Products or Deliverables:
New experimental data on sliding bearings which will, in general, be of value to designers, and a recommended procedure for establishing minimum and maximum values of the coefficient of friction for use in design.
