This 8-hour course presents a methodology to rehabilitate post-tensioned reinforced concrete box girder bridge decks using a thin Ultra-High-Performance Concrete (UHPC) overlay. While the emphasis is on post-tensioned box girders, the methodology can be extended to other bridge types such as slab on girder bridges.

Additional course detail is provided in the sections below.

• Course Topics
  • Review of previous work to rehabilitate concrete bridge decks using UHPC, including both slab on girder and box girder bridges
    
    
  • Explanation of UHPC material characterization studies and selection of a material for the overlay
    
    
  • Use of numerical modeling results to check girder stresses and deflection along with suggested modeling techniques
    
    
  • Discussions of experimental results from a half-scale specimen to demonstrate the performance of the overlay under laboratory conditions
    
    
  • Best practices to install the overlay construction specifications
• Course Outline

  [no outline provided]

   

• What you will learn

  • Importance of deck preparation to ensure overlay durability
  • Numerical modeling to check girder stresses & deflection
  • Differences between commercial & non-proprietary UHPC mixes
  • Importance of evaluating bridge response during overlay process
• Who should attend

  Anyone involved in the maintenance and rehabilitation of post-tensioned reinforced concrete box girder bridge decks, including owners, designers, structural engineers, contractors, and construction QA/QC staff.

  Charles Sikorsky, PhD, PE, UC Berkeley, Institute of Transportation Studies

  Dr. Sikorsky joined ITS after 25 years with Caltrans, where his field experience included the I-280 Viaduct Retrofit Project in San Francisco (damaged after the 1989 Loma Prieta Earthquake) and construction of the West Approach to the San Francisco-Oakland Bay Bridge. Following his assignments to Structure-Construction he joined the Seismic Research Program, which later merged into the Geotechnical-Structures Research Program, where he managed for fifteen years until retirement.

  Dr. Sikorsky has published over 40 journal articles related to bridge design and maintenance, and served as the Department Liaison to the Caltrans Seismic Advisory Board. He was an expert panel member for the FHWA Long Term Bridge Performance Program and a founding editor for Structural Health Monitoring, with research interests that include developing nondestructive damage evaluation methods to evaluate structural safety and more recently investigating the application of UHPC to rehabilitate bridge decks, including post-tensioned box girder bridges. He currently he serves as the Administrative Director for the Ultra-High Performance Concrete Initiative (UHPCi) at Iowa State University.
