Abstract

Abstract

The lateral buckling of cantilevers of doubly symmetric I-section with different boundary conditions at tip was investigated in this paper, where three boundary conditions at tip in terms of practical use, both the lateral translation and torsion displacements clamped, torsion displacement clamped and torsion displacement elastically restrained, were mainly concerned.The solutions for the buckling load of these cantilevers under two typical load cases, the uniformly distributed loads and one concentrated load at tip, were proposed, in which the effects of the beam length and loading position in the vertical direction along the cross-section on the buckling load could be considered.Comparisons of lateral buckling loads from the presented solutions and the finite element analyses showed very good agreements between each other, which indicated the good accuracy of the proposed solutions.
