From known distributions of mass, bending stiffness and shear stiffness, five natural frequencies were calculated both of the vertical- and the horizontal vibrations, with the use of a discretizing method.
In these calculations the ship was considered as a Timoshenko beam.
Bending- and shear-stiffness have been calculated extensively in a number of cross-sections of the ship.
A correction was applied for the difference in virtual mass at the higher modes with respect to that at the 2-node.
The influence of the rotary inertia has been taken into account in the form of an additional correction.
Part of the frequencies calculated was compared with measured ones. For the vertical vibration the effect of the shear stiffness was compared with the shear correction according to Prohaska [6].
