Fuzzy Comprehensive Evaluation Method for Masonry Structure Safety

摘要

摘要: 针对已有砌体结构安全性评价方法中，定性评价方法难以反映同安全等级的差异以及定量评价法运用难度大的问题，将层次分析法、模糊理论等方法应用于砌体结构安全性的综合评价，结合砌体结构的受力特点，采用三级模糊综合评价法建立了砌体结构模糊综合评价模型.利用层次分析法的基本原理，确定了砌体结构各子单元、子项和检查项的权重值，提出了其对应权向量的判断矩阵.最后，以某砖混结构住宅楼为例验证了所提出安全性评价方法的可行性.研究结果表明，本文所建立的砌体结构安全性模糊综合评价法可以全面反映各影响因素对结构安全性的影响，定量评价子项层、单元层以及结构整体的安全等级，概念清晰，便于操作.

Abstract: 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.
