Realistic nonlinear seismic analysis of corroded reinforced concrete buildings requires accurate estiınation of the bond-reinforcement slip relationships that will be used for modifıcation of moment-curvature relationships. In this study, it is aimed to develop an experimental model to estimate the adherence strength of corroded reinforced concrete columns in order to fıll the gap related to the adherence strength recoınmended in the literature based on concrete compressive strength. For this purpose, 25 reinforced concrete columns, which will be produced according to the experimental program, will be tested under cyclic lateral displacement loading at two different axial load ratios of 0.20 and 0.40, at most four different corrosion levels and for a maximum of three concrete strength levels. An accelerated corrosion method will be used to carry to the reinforcing bars embedded in the reinforced concrete columns to the targeted corrosion level within the scope of this research. The actual corrosion levels are expected to be obtained as a result of gravimetric works by breaking the concrete and removing all longitudinal and transverse reinforcement bars from reinforced concrete columns. As a result of the experimental work, it is planned to develop an experimental model to estimate the adherence strength of reinforced concrete columns that have been corroded as a function of corrosion levels.
