Investigation of Linear and Nonlinear Behaviour of Reinforced Concrete Column Exposed to Corrosion Effect for Different Damage Limit Levels

Abstract

The high performance of reinforced concrete structural elements under the effects of horizontal loads such as earthquakes is of great importance in terms of minimizing the loss of life and property that may occur due to earthquakes. One of the parameters affecting the earthquake behavior of a reinforced concrete structure is the corrosion effect. In this study, linear and non-linear behavior of reinforced concrete columns at different corrosion effect levels were investigated for damage limits. For this purpose, 5 different corrosion scenarios were considered, and the effects of corrosion exposure time and propagation velocity parameters on the seismic behavior of the reinforced concrete column were investigated. In the study, nonlinear analyzes of the column were made using Ansys software, the data obtained were determined for different damage limit levels and compared with the section analysis. As a result of the study, moment-curvature relations, lateral load-lateral translation relations, bending ductility and plastic rotation capacity of the reinforced concrete column were determined for each corrosion scenario.
