In general, the reinforcement of a structure is performed with cylinders. In this study, it is attempted to analyze the circular reinforcement with fins. And the maximum stress and deflection is investigated fur the circular reinforcement between two plates. The shape of models are : one which has only circular reinforcements of different diameters and one which has circular reinforcements with fins and one which has fin of same length and circular cylinders of different diameters. And in each model, there are two kinds; one is with upper and lower plates and the other with none. The results shows that the maximum stress is less in the model of circular reinforcement with fins than that in the model without fins. And the maximum stress of a model without upper and lower plate is less than that of a model with plates.

In general, the reinforcement of a structure is performed with cylinders. In this study, it is attempted to compare the safety Circular reinforcement with 4 fins and Honey-comb at the equal mass. Circular reinforcement with 4 fins have two kind of the models One has no hole in the upper and lower plates. The other has holes, and it is divided by 3 cases. And the maximum stress is investigated for the circular reinforcement with 4 fins and Honey-comb. The results shows that honey-comb is more strength than the others. And reinforcement with 4 fins of hole case2's maximum stress is 82% by compare 10 honey-comb.
