|Abstract:||The paper investigates the elastic buckling behaviour of columns under a combined trapezoidal distributed axial load and an end concentrated load. The buckling analysis takes into account the effects of pre-buckling shortening and shear deformation. For shear deformation, Engesser's assumption of the shear force acting perpendicularly to the centreline of the deflected column is adopted. Based on the derived incremental total potential energy functional, the finite element method is employed for solution. The effects of pre-buckling shortening and shear deformation are investigated and approximate formulas are proposed to incorporate them into the assessment of buckling loads for columns. © 1992 Springer-Verlag.|
