Abstract:Research Objectives:
• Prove through physical testing and observation that debonding strands can reduce or eliminate critical girder end cracking
• Eliminate cracking in the bottom flange of the girders, where cracks could allow moisture to reach prestressing strands and induce corrosion that might affect the girder capacity
• Provide design recommendations for effectively using debonded strands in girders
