Since at least half of all sprial galaxies contain barred features, it is important to understand how bars form and evolve. We are particularly interested in the buckling behavior of bars and possible links to pseudobulges. Using a barred galaxy potential derived from an N-body simulation, we are investigating the stellar orbits supported by the bar at different pattern speeds. Specifically, we are focusing on the stability and vertical behavior of singly periodic orbits. This poster will discuss the techniques used in this work and present some preliminary results. This work has been supported in part by a Univ. of Wisconsin - La Crosse Faculty Research Grant.
