In this paper, the buckling analysis was performed to compare the buckling mode and the buckling load for siffened plates having ㄷ, Reverse T, corrugated wave, ㄹ, honeycomb and ㅁ types of ribs. In the case of the rib space S=300mm, various types of buckling modes were appeared according to the rib types. In the case of the rib space S=450 and 600mm, the buckling loads of ㄹ, ㅁ and honeycomb were bigger than that of ㄷ and ㅁ type was the biggest.
