Abstrakt:	Corrosion of embedded carbon steel is a leading factor in deterioration of ageing conventional reinforced concrete structures. Methods to accurately predict remaining capacity of corrosion damaged elements, especially shear capacity, are lacking. In this paper, ACI-AASHTO approach, strut and tie method, modified compression field theory, and Response 2000™ were used to predict the shear strength of corrosion damaged and undamaged test beams. The methods were modified to account for the corrosion induced damage to both the concrete section and stirrups. Each of the methods considered, with the proposed modifications, reasonably estimated the remaining shear capacity of large-size laboratory specimens subjected to accelerated corrosion of embedded stirrups.
