Estimation of Prestress Force Distribution in Multi-Strand
Cho et al. observed the distribution pattern of the prestress force in the anchor heads in a series of jacking tests on a specimen 20 m in length, and proposed a method to relate this distribution of the prestress force in the multi-strand system to the measurement of the smart strand. This study was the first one to systematically deal with the distribution of the prestress force in the anchor head, but exploited a limited amount of data acquired from an experimental specimen, not field ...

Estimation of Prestress Force Distribution in Multi-Strand
However, the prestress forces developed in the strands of the multi-strand system frequently adopted in PSC structures differ from each other, which means that the prestress force in the multi-strand system cannot be obtained by simple proportional scaling using the measurement of the smart strand.
