This paper discusses behavior of plain reinforced concrete columns under eccentric loading. An experimental Investigation was conducted, where nine reinforced concrete columns has been tested under eccentric loading with varying eccentricity - three tested under zero eccentricity, three under 25mm eccentricity, three with 50mm eccentricity.. The result conforms that the eccentric loaded columns buckles more as compared to the concentric loaded columns, as the eccentricity of the columns increases the buckling of the columns also increases. The results conforms that columns subjected to larger eccentricity has more wider cracks.
