When containment vessels are subjected to internal blast loading, not only the breathing mode, but also the other vibration modes may be excited. Therefore, it is very important to understand the vibration modes in spherical containment vessels. In this paper, we present experimental results of modal analysis of a spherical containment vessel, in which the mode frequency and mode shapes are given. We also conduct the frequency analysis on dynamic responses of the spherical containment vessel subjected to three different blast loadings, in which the vibration modes excited in the dynamic vibration are found. The current study may provide further understanding on dynamic responses of containment vessels.
