Concrete is the mainly unquestionable and essential material being used in construction with developing infrastructure throughout the world. The strength of components of a structure creates stiffness regularity for the whole linkage connectivity. As the current study carried out a comparative and understandable behavior of the multistoried building column component with regular and irregular grade of concrete. A software analytical approach is used for the analysis of total five similar building models with same and different grades. Different cases show its different behavior and define its own importance of grade change. At last conclusions have drawn for the efficient and final case that shows optimal location of grade change in concrete columns in a symmetric structure. Grade location case T shows least parametric values after comparison with other grade location cases.
