3 Strength check criteria

 In general, loads shall be calculated and strength checks shall be carried out for the aft, middle and forward frames of each hold. The scantlings required for frames in intermediate positions shall be obtained by linear interpolation between the results obtained for the above frames.

When scantlings of side frames vary within a hold, the required scantlings shall also be calculated for the mid-frame of each group of frames having the same scantlings. The scantlings required for frames in intermediate positions shall be obtained by linear interpolation between the results obtained for the calculated frames.

Table 2 Bending moment coefficients ma and mb

  ma mb
hB = 0.08 h hB = 0.1 h hB = 0.125 h
Empty holds of ships approved to operate in non homogeneous loading conditions 10 17 19 22
Other cases 12 20 22 26

Note Note 1: Non-homogeneous loading condition means a loading condition in which the ratio between the highest and the lowest filling ratio, evaluated for each hold, exceeds 1.2 corrected for different cargo densities.

Note Note 2: For intermediate values of the bracket length hB, the coefficient mb is obtained by linear interpolation between the table values.
