Effects of the End-Zone Reinforcements and Strand-Debonding on the Temporal Changes of Principal Stresses at the Ends of the Hollow PC-Girders
AK Karimi, R Uchida, AM Fazli, J Tomiyama… - Materials Science …, 2022 - Trans Tech Publ
Hollow PC-girders are hollow along the length of the girder; because of this, the possibility of
developing horizontal cracking at their ends at the prestressing time is high. In this paper, a …
