Anchorage Capacity of Naturally Corroded Reinforced Concrete Beams
Paper i proceeding, 2012

In this study, the anchorage capacity of naturally corroded reinforcement was investigated experimentally. The test specimens were taken from edge beams of Stallbacka Bridge in Sweden. The beams have shown different extent of corrosion damage; from no sign of corrosion to extensive cover cracking and spalling. A four-point bending test, indirectly supported with suspension hangers, was set up so that a diagonal shear crack preceded an anchorage failure. The anchorage behaviour was examined through monitoring the applied load, free-end slip and mid-span deflection. The test results can be used to extend our knowledge concerning the structural behaviour of corroded reinforced concrete structures to field conditions.
