Authors' response

摘要

The authors are pleased to see that their work, "Comparison of Details for Controlling End-Region Cracks in Pretensioned Concrete I-Girders," has generated national and international interest, and thank Jose Marti-Vargas for his insightful comments. His comments provide a welcome opportunity to clarify and expand our discussion of the research results and to advance the body of knowledge on this highly relevant topic. Marti-Vargas inquired about the discrepancy between Fig. 6, which shows the growth and formation of end-region cracks, and the statement that web-splitting cracks were observed in specimen PT the day after prestress transfer. This discrepancy is due to an unfortunate error in our manuscript. As shown in Fig. 6, cracking in the web of specimen PT was not observed until 30 days after prestress transfer. We are grateful to Marti-Vargas for bringing this discrepancy to our attention so that we might provide clarification.
