In order to set up analytical mode of shearing capacity of deep beam and seek for more significant influencing factors, the factors have been analyzed by fuzzy comprehensive judgment, combine with the theory of fuzzy set, compare and select the Method of Determination to the Index Weight, and determine the weights of each factors. The fuzzy comprehensive evaluation has been proved to be simple and convenient by the evaluation analysis of examples, and the evaluation results are approximately identical to the actual test, which has comparable value in engineering application.
Keywords-shearing capacity of deep beam; influencing factor; fuzzy comprehensive evaluation; fuzzy modelI.
