• Abstract:
  This research result was part of a larger project entitled, “Quantifying the Effect of Prestressing Steel and Concrete Variables on the Transfer Length in Pretensioned Concrete Crossties,” conducted by Kansas State University (KSU) and sponsored by the Federal Railroad Administration (FRA). This report documents the advances made to determine the transfer length of pretensioned concrete railroad ties using non-contact (optical) strain measurement and digital image correlation. The full technical report can be downloaded from the K-State Research Exchange.
