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.
