This report describes the transition phenomena which were found in the previous studies of a thin cylindrical vessel under vertical excitation. These phenomena had the following different processes of three frequency regions in the bifurcation diagrams on the wall surface displacement of vessel. These processes were classified into shifting from periodic motion to quasiperiodic motion, the periodic resonance of parametric excitation and the characteristics of mixing the above two motions. For a detailed investigation of trajectories and spectra, critical acceleration α_p was defined by exciting acceleration immediately before the occurrence of this transition, and α_p was a new standard that estimated the transition phenomena, On the other hand, four stringers were used to induce stiffening of the vessel. The stiffening, which increased the rigidity of the vessel, restrained the quasiperiodic motion, and therefore α_p was increased.
