A Study on the Collapse of Ship Structure in Collision with Bridge Piers (3rd Report)

Abstract

In the present paper, some structural model tests were carried out, simulating the collision of ship side with the buffer placed on the corner parts of a bridge pier. We used two kinds of buffer models, referred to as grid-type and composite-type.Force-deformation curves were compared between two types of the buffer models. The composite-type of buffer was found to be effective in a side collision, as well as in a bow collision which had been studied in the previous paper. The amount of energy absorbed by this type of buffer was estimated, in both cases of a side collision and a bow one.
