The objective of this study is to find the optimal production process in the aluminum IMS core parts. To reduce the production process, the total stage was designed at a total of 2 stages and 3 stages. In the total 2 stages process, the production stage was divided into a shaft part production and a yoke part production. In the total 3 stages process, the yoke production stages were subdivided into the 2 stages for distributing the stress. The results were compared and analyzed in terms of effective stress, folding characteristics and load characteristics. The stress distributions according to the production total stages were almost the same, the yoke production stage was received high stress due to the high strain. Both the tubular shaft yoke and solid shaft yoke according to the production total stages did not have any problems in the production because there did not occur the folding, metal flow and under-fill. When the total 2 stages were employed, the load for producing the tubular shaft yoke and the solid shaft yoke was decreased by 35.0% and 27.1%, respectively. As the results, when the total 2 stages process is applied rather than 3 stages process, the product is produced quickly and it is expected to be advantageous for the production cost due to the low load.

In this study, comparative analysis has been performed with regard to a bending stress and deformation at bottom slab of a concrete floating container terminal by live load distributions. In addition, a structural performance and behavior of the floating structure is considered using a numerical analysis. Through reviewed structural performance of a floating structure by live load distribution, the structure presented tensile behavior by two live load cases (A, B, D-type). Then, the other live load cases (C, E, F, G, H, I, J-type) shows compressive behavior. Especially, immoderately compressive stress was generated on bottom slab at specific load distribution. but, that should be decreased through controling buoyancy pre-flexion. Through reviewed structural behavior, slopes of structure by four live load cases (B, E, F, H-type) were exceeded in design criteria of mega-float. It should be estimated that it get out of the load case at loading container. In all, the present study can be considered as a benchmark of a floating container terminal in the absence of analysis and will be used to guide-line about serviceability of concrete floating container terminal.
