ABSTRACT
Steel-concrete-steel (SCS) sandwich plate has been developed as the ice-resisting walls in Arctic offshore constructions. This paper investigates the ultimate strength behaviour of SCS sandwich plates under different surface loading area by numerical analysis method. This paper adopted the finite element model that was developed and extensively validated by the test results. Through the 35-case study, the ultimate strength behaviour of the SCS sandwich plate under different surface loading area was investigated. The general load-deflection behaviour of the SCS sandwich plates under different loading area were analysed and summarized. Different failure modes of the SCS sandwich plate under different surface loading area were reported and discussed. The load-transferring mechanism of the SCS sandwich plate under different surface loading area were analysed. Finally, considering the applications of these SCS sandwich plate as the ice-resisting wall in the Arctic offshore constructions, these FE predicted ultimate resistances of the SCS sandwich plates under different surface loading area were compared with the corresponding ice-contact pressure predicted by the design codes. These comparisons confirmed the applicability of developed SCS sandwich plate as the ice-resisting wall in Arctic offshore constructions.
