FOURTH NATIONAL WORKSHOP ON BRIDGE RESEARCH IN PROGRESS:
 
RESEARCH ABSTRACT
 
Title:
Pile to Pile Cap Connection Test Series
Author(s) and Affiliation(s):
Frieder Seible, M.J. Nigel Priestley and Pedro F. Silva Department of Structural Engineering University of California, San Diego, La Jolla, CA
Principal Investigator:
Frieder Seible
Sponsor(s):
California Department of Transportation
Research Start Date:
June 1994
Expected Completion Date:
August 1996
Research Objectives:
The main design characteristics investigated under this Caltrans research project are the development length and anchorage behavior of the longitudinal pile bars into the pile cap joint region; pull out of the steel jacket anchorage bars from the joint region; investigation of the levels of principal tensile stresses through the joint degradation; and development of joint force transfer mechanism models.
Expected Products or Deliverables:
The test results will be used as a guide to develop a consistent procedure for the seismic design of pile to pile-cap connections.
