Abstract

The effect of flange taper ratio on bucking load capacity of web tapered steel cantilever beams and beam-columns is investigated by performing finite element analysis. Beams and beam-columns of span 4 m, 6 m, and 8 m are considered. For all the cases, the web taper ratio is considered as 0.5. The flange taper ratios considered are 0.4, 0.5, and 0.6. Linear elastic buckling loads are obtained by performing finite element analysis with the help of ANSYS – commercial software. The beam-columns are subjected to eccentric axial loading and beams are subjected to lateral point load at free ends. By observing the obtained results, it is evident that with the increase in flange taper ratio, the buckling load is increased. The effect of flange taper ratio on buckling load is more dominant as span of the members increases.
