Abstract

Buckling analysis of a vertical structures is crucial in structural design for various loads, and simultaneously, reducing the long structures mass is essential for minimizing weight and cost. This study involves the analysis of long structures with rectangular and circular cross-sections under compressive loads, calculating the buckling load multiplier. Additionally, hollow rectangular and hollow circular columns are designed and analyzed under the same load and boundary conditions as the solid counterparts. By varying the hollowness of the rectangular and circular columns, the buckling load and the percentage of mass saved compared to solid columns are determined. At the same volume of material, the rectangular structure exhibits a 3% higher load multiplier than the circular structure. Increasing mass reduction by introducing hollowness also decreases the buckling load multiplier.
