| Abstract: | The fatigue strengths of concrete were predicted hy integral GM(1,1) forecting model in this paper, and the prediction results were indentical with experiments. It was evident that the discrete data sequences, such as fatigue strength of concrete full of wave preperty, would be predicted accurately by integral GM(1, l)model. And it is worthy to popularize this Grey System Theory. |
