THE DYNAMIC CHARACTERISTICS OF UNSYMMETRICAL SHIP STRUCTURES

In idealizing a ship structure, it is usual to assume port and starboard structural symmetry about the longitudinal center line. In this paper, this restriction is relaxed and the influence of asymmetry of structure is assessed by reference to the dynamic characteristics of an idealized aircraft carrier. However, prior to the commencement of the evaluation of the dynamic responses, structural parameters need to be determined and in an appendix, procedures are described for their assessment when the structure is asymmetrical.
