Quantitative analysis of slab bridge damage based on Mamdani fuzzy reasoning with fusion of WM algorithm
In order to quantitatively analyze the damage degree of local position of the slab bridge,a quantitative analysis method of slab bridge damage based on Mamdani type fuzzy reasoning with the fusion of WM algorithm was proposed.The u-nique relationship between the influence surface index and the damage degree was explored,and the damage degree of slab was calculated and analyzed by MIDAS and Python simulation.The results show that the fuzzy logic system has a very good memory ability.When the WM algorithm is integrated into the fuzzy logic system,the damage degree of slab bridge can be ac-curately identified regardless of single-point damage or multi-point damage.When the WM algorithm is not integrated,because its fuzzy rules do not perform the confidence calculation,the wrong rules are also calculated,which eventually leads to a de-crease in the accuracy of quantitative results.The research results can provide a more scientific and accurate basis for the damage assessment and maintenance strategy of the slab bridge structure.
