Reliability Appraisal On Ancient Stone Pagodas Based On Fuzzy Composite Appraisal Theory

Chinese ancient stone pagoda is an outstanding representative of Chinese ancient high buildings, which syncretizes the elites of Chinese traditional architectural art and external culture, and also has deep significance in history, art, science and praxis. Now, our nation has no well-rounded criterion of reliability appraisal. Under such a history background, a rating system of ancient stone pagodas' reliability appraisal based on fuzzy composite appraisal theory is established. The main research contents are as follows:1. According to the analysis of the construction features and the damaging effect factors of ancient stone pagodas, a reliability appraisal method of ancient stone pagodas is established combining macro research and quantitative check.2. As a combination of existing reliability appraisal criterion, 10 indexes in total of foundation soil, foundation and superstructure are selected to have established the index system of ancient stone pagodas' reliability appraisal, and the appropriate classification standard is given. The subordination function is built based on fuzzy mathematics theory. The analytic hierarchy process determines the weight value of every factor. Using the weighted average model as a comprehensive evaluation, the ultimate reliability level is determined according to the approach degree method.3. As an example, Dinglinsi Tower in Nanjing City is illustrated by using this method. Compared with the practical situation, the result shows that the rating system which is established in this paper is feasible.
