Overview
This workshop will review the latest developments in bridge design practice and LRFD, and provide information about available resources from AASHTO/FHWA and KDOT.
New trends in concrete bridge design and construction will be presented. The workshop will address innovative issues related to prestressed (P/S) concrete bridges, which include the Nebraska Sections, use of Self-Consolidating Concrete (SCC), and recent research on bond and development length of rebars and strands in P/S concrete in general, but particularly in SCC.
Design for continuity including simple P/S girders made continuous through composite deck action, bridge rating and available software, and substructure design using LRFD will be discussed.
A short presentation on tied-arch bridges, a discussion on lessons learned from innovative bridge experiences such as spliced girders and other new ideas being promoted, and a comparison with more traditional approaches such as steel plate girders will conclude the workshop.
Presentations will be made by bridge/transportation officials, researchers, consultants involved in design and plans preparation, and fabricators or contactors responsible for bridge construction.
Topics will include:
- Nebraska P/S Sections
- Self-Consolidating Concrete (SCC)
- Bond and Development Length
- Design for Continuity
- Bridge Rating and Software
- Designing Substructures with LRFD
- Tied-Arch Bridges
- New Ideas: Successes or Failures - Discussion
