Determining Bond-Slip Characteristics of Prestressing Tendons with Varying Geometries in Two Concrete Mixtures

Untensioned pullout tests were conducted to obtain the bond-slip characteristics of two groups of prestressing tendons used in concrete railroad tie production. The purpose of this testing was to provide empirical data to support numerical methods of predicting splitting and bursting failures in...
