Abstract

In order to study the constitutive model of bond-slip between prestressed steel strands and concrete, pullout tests were designed with 1×7Φ15.2 mm and 3×7Φ15.2 mm concrete specimens. The influence of the number of steel strands on the failure mode, slip characteristics, and concrete strain of pullout specimens was analyzed, and the bond mechanism of 3×7Φ15.2 mm prestressed steel strand bundles was clarified.
