FOURTH NATIONAL WORKSHOP ON BRIDGE RESEARCH IN PROGRESS:
 
RESEARCH ABSTRACT
 
Title:
Innovative Prestressed Steel Composite Short to Medium Span Bridges
Author(s) and Affiliation(s):
Dan Burroughs and James Lockwood, J. Muller International, Chicago, IL Joseph Hartmann, American Iron and Steel Institute, Washington, D.C.
Principal Investigator:
Dan Burroughs
Sponsor(s):
American Iron and Steel Institute
Research Start Date:
Fall 1995
Expected Completion Date:
June 1996
Research Objectives:
This study reviews methods to combine both prestressing, high-performance steel and composite concrete decks to improve bridge performance, constructibility, aesthetics, and economy. Initially, a total of eight bridge concepts have been developed in the short to medium span range using innovative concepts of prestressing and high-strength steel. Three bridge concepts have been developed to the preliminary design phase including plan details and cost estimates. Single and two-span bridges with span lengths of between 100 to 180 feet have been studied. The alternates developed use prestressing both longitudinally in the main structural components and transversely in the deck.
Expected Products or Deliverables:
A final report with specific recommendations, bridge layouts, cross-sections, details, and cost estimates for three of the prestressed steel composite bridge alternates.
