The requirements for inelastic lateral buckling restraint of H-section beams or beams restrained at top flange are reviewed.
This study permits the finite element method can be applied on the problems of lateral buckling of beams under various
conditions of loading, location of load, and end restraint. The accuracy and convergence of the suggesting method is
demonstrated by studying the structural behavior of the lateral buckling of simply supported beams with non restraint, beams
with a central elastic restraint possessing either lateral or torsional stiffness, and beams with restraint by deck plate attached to
top flange. The results of this finite element study are in reasonable agreement with previous approximate method suggested by
Clark, Lawson and Mutton. Also it is compared with the experimental result of Lawson's test.
