RESEARCH ABSTRACT
 
Title:
Three-Dimensional Modeling of Stiffness Characteristics for Highway Bridge Abutments
Author(s) and Affiliation(s):
John C. Wilson, Department of Civil Engineering McMaster University, Hamilton, Ontario, Canada Michael Justason, Berminghammer Foundation Equipment Ltd. Hamilton, Ontario, Canada
 
Principal Investigator:
John C. Wilson
Sponsor(s):
Natural Sciences and Engineering Research Council, Canada
Research Start Date:
September 1993
Expected Completion Date:
September 1996
Research Objectives:
The objective of this study is to develop simple techniques for inclusion of abutment stiffness characteristics in seismic bridge analysis.
Expected Products or Deliverables:
Simple relationships describing linear elastic stiffness or typical abutment systems; a basic understanding of the contribution of abutment systems to total bridge response; correla-tions with seismic data of bridge responses; and a simple yet realistic starting point for including nonlinear effects in abutment analyses.
