Strength Behavior Analysis of Insert Plate for Placing Corner Fitting due to Container Load

Abstract

Abstract Currently, the ship container generation has allowed for the carriage of containers on deck up to four tiers high. The container loads in tiers high affect on deck structure. Consequently, an insert plate is used and located on the top of the ship deck structure for placing the container corner fitting. Sometimes container fitting is placed between longitudinal deck beams under without supporting construction such as pillar or carling. Therefore, this matter should be analyzed to obtain the strength behavior of the insert plate. This study describes the strength analysis using the finite element method (FEM) through ANSYS software. Based on the simulation results, the maximum Von Mises stress of the insert plate was obtained exceeds 181 N/mm 2 and 235 N/mm 2 in the initial condition, whereas the insert plate could support only 15% loads per corner fitting (three tiers high). Then, the thickness addition of the insert plate until 24 mm reduced the stress, however, the reduction was a small magnitude. By adding two carling construction is similar to the size of a transverse deck beam, under the insert plate, the stress was obtained 138.54 N/mm 2 .
