Hull girder shear strength assessment is one of the important checks for hull girder strength along the full length of the hull girder. Recently released IACS UR S11A greatly increases the wave shear force for container ships. However, in SOLAS or Class rules, there is no clear requirement for how to accurately simulate the still water shear force for container ships. In this paper, two approaches of modeling containers¡¯ weight are compared. Big deviations are found at the region of transverse bulkheads for typical container ships with uniform load modeling approach and point load modeling approach. Uniform load modeling approach underestimates the extreme value of vertical still water shear force. The results verified in global finite element analysis show that point load modeling approach is more reasonable to simulate the still water shear force for container ships. At the same time, some useful conclusions are summarized for loading manual with point load modeling approach.
