Determination of Buckling Load for Columns with Varying Section - an Approximate Easy Procedure for Certain Cases

A numerical procedure based on the successive approximate method is used for the determination of elastic buckling loads of columns. For the two cases, (l) columns hinged at ends, and having a symmetrical variation of moment of inertia (if section varies); and (2) columns with constant or varying section, fixed at one end and free at the other; it is shown that the major calculation involved in the method, which is the determination of deflections, can be easily and mechanically done. Thus the determination of elastic critical load for such columns becomes very easy and is illustrated in four worked examples. Prakash Desayi
