Assessment of Anchorage Capacity of Naturally Corroded Reinforcement

Paper in proceeding, 2013

In this study, the anchorage capacity of naturally corroded reinforcement was investigated. Fourteen specimens with different degrees of corrosion-induced damage were taken from northern edge beams of Stallbacka Bridge in Sweden. All damage including cracking and cover spalling were carefully documented before testing. A four point bending test with suspension hangers at the supports was utilized. In all experiments, diagonal shear cracks preceded the expected splitting-induced pull-out failure. The anchorage behaviour was monitored through measurements of the applied loads, deflections and main bar slips. Combined with the authors’ previous findings, these results increase the knowledge regarding the structural behaviour of corroded reinforced concrete.
