An analysis is presented for the free vibration of simply supported. longitudinally stiffened prismatic shells, in which the transfer matrix technique is used. The governing equations of vibration of a plate (a side wall) are written in a matrix differential equation by use of the transfer matrix of the plate. The transfer matrix is determined by numerical integration of the equation, and the entire structure matrix of the shell is obtained by the product of the transfer matrix of the plate and the point matrix at the joint between two plates and a stiffener. The frequency equations are derived in therms of the elements of the structure matrix. By the application of the method, the natural frequencies (eigenvalues of vibration) and the mode shapes are calculated numerically for rectangular prismatic shells with structural symmetry, and the effects of the stiffeners on the vibration are discussed.
