Transfer Length of CFRP/CFCC Strands for Double -T Girders

摘要

Presents the results of an experimental investigation addressing the variations in transfer lengths in two types of carbon fiber reinforced polymer (CFRP) prestressing strands. Parameters such as he level of prestress at release, creep, and the rate and method of release of prestress are considered. In all, eight double -T (DT) prestressed girders fabricated with high strength concrete were tested.
