Reinforced concrete columns in building structures are subjected to combined axial loads and uniaxial or biaxial bending or both. In a geometrically nonuniform member, variation in cross sectional dimensions may be either continuous over the entire length of the member as in tapered members or may occur at discrete points as in stepped members, since neither axial load nor stiffness is constant along the column height the stability analysis of a stepped column is usually more complicated than that of a uniform column. The present study deals with the comparison of Concentric Non-Prismatic columns and Stepped columns under the effect of static and dynamic loads with the help of ETABS Software.

Keywords: Non- Prismatic Columns, Stepped Columns, Column forces, Base Shear, Displacement, Inter-Storey Drift.
