FOURTH NATIONAL WORKSHOP ON BRIDGE RESEARCH IN PROGRESS:
 
RESEARCH ABSTRACT
 
Title:
Evaluation of Bridge Abutment Stiffness During Earthquakes
Author(s) and Affiliation(s):
Rakesh K. Goel Department of Civil and Environmental Engineering Syracuse University, Syracuse, NY
Principal Investigator:
Rakesh K. Goel
Sponsor(s):
Currently unfunded (Initial research was jointly supported by CSMIP and Caltrans with Dr. A.K. Chopra, University of California, Berkeley, as PI)
Research Start Date:
June 1993
Expected Completion Date:
June 1998
Research Objectives:
The objectives of the research are to develop a simple procedure for estimating stiffness of abutments in short-span bridges directly from their motions recorded during earthquakes, and to evaluate and improve the current abutment modeling procedures for earthquake analysis and design of such bridges.
Expected Products or Deliverables:
The products expected are a simple analytical procedure to estimate the abutment stiffness of short bridges directly from their motions recorded during earthquakes, an evaluation of current industry practice on estimating the stiffness of abutments in bridges with integral abutments, and recommendations for improving industry practice.
