Abstract
No reasonable and desirable calculation formula has been provided up to this time for the stress caused by earthquake in the hollow cylindrical shell. Therefore, in this paper the author proposed both of general and practical calculation formulae of stresses due to the forced vibration, solving the well-known three simultaneous equations of motion, and introduced the stress calculation graphs by means of which the stresses caused by earthquake in the reinforced concrete hollow cylindrical structures can be calculated. In addition, some discussion was given to the damage of the fodder storage silos which was damaged by the great earthquake of 1952 at the southeastern district of Hokkaido so called Tokachi-Oki Earthquake.
