摘要：

The exact solutions for the stability analysis of a one-step bar of varying cross-section subjected to concentrated and distributed axial loads are found first. Then the exact solution of that bar is used to derive the eigenvalue equation of a multi-step bar of varying cross-section subjected to more complicated loads by using transition matrices. All of the exact solutions are expressed in terms of Bessel's functions and super-geometric series.
