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. WebThe problem of determining that shape of column which has the largest critical buckling load is solved, assuming that the length and volume are given and that each cross section is convex. The strongest column has an equilateral triangle as cross section, and it is tapered along its length, being thickest in the middle and thinnest at its ends. Its …

Flange plate moment connections are a vital part of steel construction, providing a secure way to join beams, columns, or girders and transfer axial and moment loads between them. These connections are designed to withstand the stresses placed upon them, ensuring the overall structure can handle the load conditions.
WebConcrete-Filled Double-skinned Steel Tubular columns (CFDST) are proved to possess exceptional structural resistance in case of fire and multi-hazard situations. This superior quality of CFDST makes it preferable in long column applications. However,
