To get the typical ship structures longitudinal bend stress in hogging condition, standard method and finite element method, two kinds of longitudinal strength calculating methods are studied and compared in this paper, the section elements of typical ship structures are calculated, the cabins finite model are established by ABAQUS, the stress distribution moiré topography are obtained, and the two methods are compared, get the following conclusion: for the section which has a regular shape, such as bottom plate, strength deck, the calculation results from the two methods are consistent; for the section which has a complex shape, such as bilge board, the results of finite method is more accurate than standard method; in standard method, for the section which has a large vertical height, such as side plate, dividing it into some plate units can enhance the calculating accuracy.
