The influence of step changes in cross-section of beams with different boundary conditions on their dynamic stability was investigated in the paper. The change in the crosssections took place in an optional location along the beam length. The investigated beams were axially loaded by a force in the form P(t)= P0+Scosνt. The problem of dynamic stability was solved by applying the mode summation method. The obtained Mathieu equation allowed the dynamic stability of tested systems to be analysed. The analysis relied on testing the influence of step changes in beam cross-sections and their locations on the value of coefficient b in the Mathieu equation. The considered beams were treated as Euler- Bernoulli beams.
