In this paper, the systematic analysis of the strength and deformation and the reinforcing effect of rings as a whole is discussed, utilizing the method introduced by this author. Consequently, it is found that the influence of the distance between rings is remarkable. When the distance is consider-ably large, the behavoir of the stress and deformation becomes very complicated near the rings, large axial bending stress occurs at the ring portion, and the reinforcing effect of rings is localized. On the other hand, when the distance is very small, the magnitude of the stress and deformation of the shell at any portion between rings becomes almost equal, and the reinforcing effect of rings extends in the entire region of the shell. This finding indicates that the investigation for the local bending is not sensible, and the probability of constructing an optimum structure in the case of using a short ring pitch exists. Therefore, the latter subject will be discussed in a forthcoming paper.
