Abstract
This paper presents a method in which, the exact and simple calculation for
finding the plates buckling load of orthotropic box columns acted on by axial
load is possible. First, the differential governing equation for the deflection of
orthotropic plates having the semi-rigid connections at two parallel edges and
two simply supported on the loaded edges were solved parametrically and
afterward the characteristic equation of buckling load was defined. Now, having
used this equation, the diagrams were plotted to determine the plates buckling
load while considering the rigidity of the semi-rigid connection. Since the
procedure for finding the local buckling load of box columns is very
complicated, a method was produced to equilibrium the critical load of the box
section with the crit
