Abstract
The principal objective of this study is to examine techniques for the analysis and design of composite icewalls for arctic offshore structures. Previous investigators have conducted numerous tests of composite beam specimens and have developed sophisticated nonlinear finite element models. Conventional reinforced concrete design methods are applied to the problem, and a method for determining the stiffness of a composite icewall is presented and compared to experimental results. This method is used to create a linear finite element model of a two‐way icewall. This linear model is subjected to ice pressures determined by the contact area and the most severe load condition is identified. The model is also used to investigate the influence of the stiffness of the structure supporting the icewall. Shear strength is evaluated, and a new scheme for integrating shear reinforcement, plate stiffening, and shear connection is presented. This scheme allows shallow section depths because the need for welder access i...
