This paper presents free vibration analysisof stiffened thin-walled structures.
Variation of well-established finite strip method, namely compound strip method, is used
for the analysis. This method is semi-analytical procedure which allows modelling of
longitudinal and transverse stiffeners within the flat shell finite strip. Influence of stiffeners
is introduced through their interface lines via appropriately calculated rigidity and inertial
properties. Main advantage of this method is its efficient modelling of transverse stiffener
within the harmonic finite strip method. Numeric analysis is carried out with one
illustrative example given here. The results obtained are in excellent agreement with the
ones from the finite element method. For prismatic structures, presented procedure
promises better insight into analysed problems than other purely numerical methods.
