Prestressing Steel and Concrete Variables Affecting Transfer Length in Pretensioned Concrete Crossties
- Federal Railroad Administration
This report highlights advances in understanding the prestressing steel and concrete properties that affect the transfer length (TL) in pretensioned concrete crossties. Transfer length values in pretensioned concrete ties are highly dependent on the type of wire indentation pattern used and the concrete strength at the time of detensioning. ASTM Standard A1096 pullout values and the correlation expression developed in this study can accurately predict the resulting TL.
