ぎ装用ダブリングプレートに関する一考察

抄録

Generally, a doubling plate has been used as an equipment support member. In designing the doubling plate, designers have to pay the particular attention how to decrease the stress concentration, but there are no official rules and no standards. In the present paper, the theoretical an analysis has been performed by finite element method. As the results of our investigations, followings can be concluded. (1) The doubling plate gives an appreciable influence on the structural stress concentration under the longitudinal bending stress. (2) HT steel need not be chosen for the doubling plate.
