| Abstract: | An approach to safety assessment of long-span concrete-filled steel tube (CFST) arch bridge based on fuzzy-neural network is presented. A three-layer fuzzy-neural network model is set up through the combination between the fuzzy-neural network and the assessing information of the long-span concrete-filled steel tube arch bridge, and the expert experience is included in this model by training the fuzzy-neural network. The approach is illustrated for the long-span concrete-filled steel tube arch bridge in Wuhan of China. The result is shown that the approach is high potential and practicality in order to assess the safety of long-span concrete-filled steel tube arch bridge. |
