ABSTRACT
This chapter is concerned with the elastic buckling of cantilevers of doubly symmetric or monosymmetric cross-section under end moments, end loads, or uniformly distributed loads, and the effects of load height from the shear centre axis. It discusses the effects of concentrated and continuous restraints. Cantilevers with end moments which cause uniform bending are rare in practice, since most loading actions are by loads rather than moments. End warping is usually assumed to be prevented at the supports of cantilevers by rigid restraints to the flanges. When the end moment rotates with the cantilever, then the relative positions of the buckled cantilever and the end moment are the same as those of half of a simply supported beam in uniform bending. Any reduction in the stiffness of the torsional restraint at the support will cause a corresponding reduction in the buckling resistance. Translational restraints were found to be comparatively ineffective, except when acting at the end of the top flange.
