Soviet studies indicate that the least reliable structural elements of a ship are intercostal members. These intercostal members, which are subject to cracking from high stress concentration and accounted for a significant portion of all damage during the 20-year period studied, are found in regions where superstructures, houses, longitudinal coamings and various cutouts end; at plate element intersections forming rigid points; and in regions where longitudinal discontinuous coamings are joined to houses and superstructures. One approach to eliminating cracking is improving the shape of intercostal members and installing reinforcements. A newer approach is advocated by the authors, that of using moving joints with pliable butt plates to redistribute stresses to adjacent structures.
