About the corrugated bulkhead on ship's construction, we have first defined its elastic modulus and rigidities, then solved the deflections of it using of consideration substituting that bulkhead with orthogonal aerotropic plate and compared them with those of experiment. We can, at the results, decide the method to be useful for its approximate calculation. As we cannot, however, determine the deflection so easily as expected by it, we produced at last other more simpler formula than that of former method taking advantage of the effective width. After applying this formula to calculate the deflection and stress, then comparing them with the experimental results we have obtained some final conclusions about that bulkhead. (1) The beam having section of one pitch wave with which the corrugated bulkhead is constructed, generally may be thought being that of simple beam theory if it has the effective width of the point at which the maximum bending moment would be happened, through all length of that beam. (2) Stress for lengthwise direction may be solved being such a problem as that determined statically or unstatically on simple beam theory.
