  • As the qualitative evaluation methods cannot reflect the differences of the same security level in the evaluation of masonry structure safety whereas the quantitative evaluation methods are hard to apply, the analytic hierarchy process and fuzzy theory were applied to the comprehensive assessment of masonry structure safety. According to the mechanical characteristics of masonry structure, a fuzzy comprehensive evaluation model of masonry structure was built by using the three-level fuzzy synthetic evaluation method. Based on the basic principles of analytic hierarchy process, the weights of each subunits, sub-items and check-items of masonry structure were determined, and the judgment matrixes of corresponding weight vectors were presented also. Finally, the feasibility of the proposed safety evaluation method was verified by a case study of a residential building of brick-concrete structure. The results show that the fuzzy comprehensive evaluation method can fully reflect all influential factors on structure safety, quantitatively evaluate the security levels of subunit layer, sub-item layer and whole structure, and is easy for operation.
