Guideline

 It has been determined that there are deficiencies in the loadings given in tables I and II of part C, section I(C), pertaining to the strength of grain divisions loaded on one side. Therefore, when it is necessary to use these tables, reference should be made to MSC/Circ.363, a copy of which is appended to these guidelines. Also, it should be noted that the loads specified in the tables in MSC/Circ.363 are expressed in Newtons per metre length and not kN as marked.

h = height of grain in metres from bottom of the division. 1/
B = transverse extent of the bulk grain in metres.
a. For values of h equal or less than 6.00 m the force shall be determined by linear interpolation or extrapolation as necessary.
b. For values of h exceeding 6.00 m the force shall be determined using the values of p/h2 given in table I.1
                 
1/ Where the distance from a division to a feeder or hatchway is 1 m or less, the height shall be taken to the level of the grain within the hatchway or feeder. In all other cases, the height shall be taken to the overhead deck in way of the division.
