Structural models of short length (1/2+1/2 hold, say) are often adopted for the stress analysis in a transverse section, so that the longitudinal bending is to be excluded maintaining the structural continuity in ship longitudinal direction.
On the other hand, the longer structural model (1 hold, 1/2+1+1/2 hold) or a complete hull model is used so as to consider the alternate loading condition or to investigate the stress combination due to longitudinal and transverse strength of ship.
