Buckling loads can be determined experimentally or by way of a prediction without actually loading the material to critical load. Mechanics of Solids & Structures – D,W.A. Chapter 9: Column Analysis and Design Introduction Columns are usually considered as vertical structural elements, but they can be positioned in any orientation (e.g. Thus all column designs are to be carried out using the strut curves given in [Fig. diagonal and horizontal compression elements in a truss). Long Column When the ratio of effective length to the least radius of gyration is greater than 45, then it is called a long column. Materials having different properties have different buckling loads which is a function of the length of the column and the second moment of area of its cross section.
