Abstract

Based on a comprehensive assessment theory, soil-superstructure interaction problem is analyzed by second-level evaluation of comprehensive evaluation. By applying comprehensive evaluation method fuzzy theory model of soil-superstructure interaction is built. Considering digital issue of the fuzzy theory model, incompatible principle of fuzzy mathematics and response by parameters change of interaction system on structural displacement fundamental factors are chosen. Fuzzy distribution method is used to establish membership function of different grades for fundamental factors. According to the different factors in the evaluation function, evaluation matrix is established and the appropriate weight is determined by fuzzy grade analysis. It is show that fuzzy mathematics method is appropriate for this kind of soil-superstructure interaction problem.
