Abstract
Progressive collapse, which is disproportional to the extent of initial damage, often brings a serious damage, even final failure to the structure, so it has attracted widespread attentions over the engineering field. In the design of offshore jacket structures for resisting progressive collapse, it is very necessary to evaluate the effect of each component on the whole structure, so as to recognize the critical components. In this paper, we present two kinds of evaluating indexs for the key component, respectively from the stress and the overall deformation energy point of view. Further, we study two different pattern of jacket platform structures, K-type and X-type, and calculate the index of each component. By using the method of removing component, we analyze the existing law of key components for different jacket type, and if we can enhance them, it will be great help to avoid progressive collapse of the jacket platform.
