Determining Slipping Stress of Prestressing Strands in Confined Sections

摘要

Based on the experimental results reported by Shahawy and Issa, the discussed paper studies the appropriateness of a modified equation presented by the authors for the development length of prestressing strands that accounts for the effect of confinement stress in confined sections. The authors should be congratulated for producing a detailed paper, which is acknowleged by the discusser. Some findings are interesting to the discusser, who would like to address the following comments for the authors' consideration.
