Free vibration of grid stiffened circular cylindrical shells is investigated based on the first Love’s approximation theory using Galerkin method. Full free edges are considered for boundary conditions. Anequivalent stiffness model (ESM) is used to develop the analytical solution of the grid stiffened circular cylindrical shell. The effect of helical stiffeners orientation and some of the geometric parameters of the structure have been shown. The accuracy of the analysis has been examined by comparing results with those available in the literature and finite element approach.
