Abstract
In civil engineering applications columns with variable cross-sections are commonly used for various reasons and buckling has a very important role in the design of these members. In this investigation square columns with variable cross-sections and circular columns with variable cross-sections is considered. These examples evaluated for four different strength classes of normal strength concrete and four different boundary conditions. ANSYS Parametric Design Language codes are developed to analyze the columns with variable cross-sections models systematically and obtained results are presented with tables and graphics. It has been revealed that boundary conditions and the shape of the cross-section effects the stability of the columns dependent to the critical buckling load values.
