In the previous paper, he showed the calculation method of the effective breadth of the stiffened plating in which web frames, and ordinary frames were arranged regularly. But the method is not practical, for the more the numbers of ordinary frames arranged between web frames increase, the more becomes complicated in caluculation. And so, in this paper he shows the simplified method assuming that: (1) The numbers of ordinary frames, arranged between web frames, are infinite. (2) The normal stress and reaction induced in the joint of stiffener and plate are same for every ordinary frames. Comparing the calculation performed both by the previous exact method with that of the present simplified method, the errors between them are abaut 2%, as shown in Table 4, if the numbers of ordinary frames are more than three.
