Abstract

In truss structure with fuzzy parameters of the random seismic analysis, the expression for the fuzzy numbers is through the decomposition theorem of fuzzy sets or extension principle to fuzzy-valued functions transplanted up, and this analysis´s method causes the very major difficulty for the fuzzy number research work. This method of using information entropy makes the fuzzy structure into a random structure dynamic analysis, and a case analysis shows that the information entropy method to analyze the network structure of fuzzy random seismic reflection is feasible.
