Öz

In this study, the
unimodal optimality conditions for axially compressed shear deformable columns
are formulated and the optimal design problems defined are numerically solved
using an iterative procedure based on the finite element method. The results
presented show that the optimization results are more reliable than the ones
obtained using classical beam theory as cross-sectional  area does not vanish at points where the
bending moment is equal to zero.
