Integrated view of methods in buckling analysis

Abstract

An integrated view of numerical techniques for determining the elastic buckling load of structural members is presented. The commonly used techniques can be grouped under two main approaches, viz. the static-kinematic approach and the work-energy approach. Each technique is described briefly and its advantage highlighted. More importantly, the connecting paths between the various techniques are discussed. An understanding of the integrated view and the techniques will provide a greater flexibility for solving buckling problems by employing the most expedient technique for solution. The various methods may also be used independently to solve the same problem to confirm the accuracy, validity and convergence of the solutions.
