Lateral vibration of pipes conveying fluid reveals various dynamical features, and has been the subject of research as an essential model of unstable phenomena in a continuous system for many years. Many studies have focused on the dynamics of pipes with intermediate spring supports. One of the reasons why this system fascinates many researchers is that the presence of double degeneracy (the pitchfork and Hopf bifurcation points) can produce a sequence of bifurcating motions. Standing pipe conveying fluid is also a system that can give rise to such double degeneracy. In this study, we consider a standing pipe conveying fluid. An additional mass is attached at the upper free end to easily produce the double degeneracy. We experimentally investigated the effects of the additional mass on the non-planar pipe motions and observed some non-planar motions.
