 buckling load 
Abstract
Slender beamcolumns loaded by axial compressive forces may buckle when the forces exceed the buckling load. This critical load strongly depends on the beamcolumn's support boundary conditions. During structural design, these conditions are, at most times, assumed to be constant. In technical structures, however, boundary conditions are mostly imperfect and may vary during operation, so that the buckling load becomes uncertain. In this paper, uncertainty in the buckling load of a beamcolumn with circular crosssection due to varying support boundary conditions and varying crosssection radius is investigated mathematically. The buckling load is calculated for independently varying support boundary conditions of either one or both beamcolumn supports as well as different slenderness ratios. The analysis shows that the influence of uncertainty in the rotational support stiffness and the crosssection radius has major effects on the buckling load of the considered beamcolumn.
