Column buckling with tapered cross section
WebFormulas and graphs for the determination of the critical elastic buckling loads of uniformly tapered columns having wide flange, box section, and other cross-sectional shapes are presented herein. Columns with pinned ends, fixed-free ends, fixed-pinned ends, and fixed ends are considered. Webof the column. This suggests that a column with a tapered cross section that is stiffer in the middle than at the ends can be more efficient (i.e., have less mass for a given …
