Abstract:
Experimental investigations into the collapse behavior of a box-shape hull girder subjected to extreme wave-induced loads are presented. The experiment was performed using a scaled model in a tank. In the middle of the scaled model, sacrificial specimens with circular pillar and trough shapes which respectively show different bending moment-displacement characteristics were mounted to compare the dynamic collapse characteristics of the hull girder in waves. The specimens were designed by using finite element (FE)-analysis. Prior to the tank tests, static four-point-bending tests were conducted to detect the load-carrying capacity of the hull girder. It was shown that the load-carrying capacity of a ship including reduction of the capacity after the ultimate strength can be reproduced experimentally by employing the trough type specimens. Tank tests using these specimens were performed under a focused wave in which the hull girder collapses under once and repetitive focused waves. It was shown from the multiple collapse tests that the increase rate of collapse becomes higher once the load-carrying capacity enters the reduction path while the increase rate is lower before reaching the ultimate strength.
