What is meaning of Scantling?

Initial Scantling Criteria for Transverse Strength

 Ship hull is subjected to static and dynamic hydrostatic pressure in its bottom and two sides, and under loads due to weight of the cargo inside the hull as shown in figure. The transverse loads may cause cross-sectional deformation as shown in dotted lines, and stresses in transverse bulkheads, floors, side frames and deck beams. In general, hulls of the cargo ships are based on transverse system where the transverse strength may be modeled as two-dimensional frames. The two-dimensional frame is subjected to the hydrostatic pressure and loads due to cargo weight as shown in Figure below , as well as the shear forces transferred from thelongitudinal members.
