In this paper we discuss the discrepancies between results reported in the literature in the context of dynamics of shell structure composed of three intersecting plates. The shell structure is subjected to a system of spatially uniformly distributed dead loads of prescribed time variation. Once the forces die out, the structure experiences free motion. The comparison of reported solutions from the literature shows that the total energy in free motion has different values, despite the fact that the same material, geometry and loads have been used. The aim of study is to address the issue by referring own results to that known from the literature. Copyright © 2008 John Wiley & Sons, Ltd.
