Corrosion is one of the most important factor to achieve in completing the service life of reinforced
concrete structures also cause significant losses in energy damping capacities of structures. In this
study, the reinforced concrete column designed in ½ geometrical scale was subjected to accelerated
corrosion test for 26.5 days under 1 ampere constant current. As a result of the experiment, weight
loss and strength reductions was obtained. Loss of strength in reinforcement due to corrosion
damage was obtained with experimental procedure. Loss of cross section and reduction of
compressive strength of concrete were obtained with empirical formulas in the literature. Thanks
to this data, 3 different scenarios applied on a sample building in Hatay province. Static pushover
analyzes of the sample building designed in accordance with the regulations were carried out with
Sap 2000 program under the specified corrosion scenarios. The load-displacement curves obtained
by the scenarios are compared with the curves of the reference building. As a result of the
comparisons, it was observed that corrosion damage caused significant loss in horizontal load
carrying capacity of the building. The corrosion scenarios show that corrosion in columns or beams
changes collapse modes of the structure.
