摘要：The authors are developing the simple and easy structural design system which investigates rapidly the design spiral in the stage of early design. In this system, initial scantlings and dimensions are determined through the total strength analysis system before performing FE analysis. The shear flow analysis is carried out by identifying the cross-section shape of hull girder using the number of representative points in a cross-section, the shape of closed circuits and the property of the shear flow on each member.The coefficients of the expression to shear flow distribution are automatically calculated. However, to apply this analysis to more complicated and various cross-sections within fore and aft portion of ships, it is important to develop a more generalized shear flow analysis method.In this paper, the authors propose a new shear flow analysis method using the basic concept of graph theory, where a pattern of networks is expressed by connections between points and edges, mainly applied to electric circuit network.In this first report, the authors give a concrete description for the formulation of the new analysis and the analytical procedure using a cross-section with three closed circuits.
