| Abstract: | The thermal buckling of columns with five kinds of boundary conditions is analysed. We haveestablished in this paper:(1) the relations between thermal buckling displacement,temperature differenceand flexibility;(2) the relations between restrained forces(intemal force).temperature difference and flexi-bility. It is also pointed out in the paper that Euler's critical temperature difference is an inferior limit of ther-mal buckling problems. |
