The cause of failure in light plating forming a part of the dock house structure lying above the main deck of 10,000 ton cruisers is shown to be due to the fact that the ship structure behaves as a bent beam, thus requiring that the highest stress occurs at the points most distant from the neutral axis. Consequently, failure occurs in the light deck house walls. This failure can be prevented by two methods: (1) use of plating heavy enough to decrease materially the deformation of the ship; or (2) modification of the ship structure in such a way that light superstructure not forming a part of the strength structure of the ship will not be forced to undergo the stress in the deck house walls only insofar as it stiffens the main structure of the ship.
