Safety Assessment of Brick-Concrete Structure Self-built House Based on Combination Weighting Cloud Model
Considering the complexity of the structural system and the fuzziness of the evaluation indi-cators,a safety assessment method based on the combination weighting cloud model is proposed to accurately evaluate the security of brick-concrete structure self-built house.Firstly,the safety assess-ment indicator system is constructed from seven aspects:foundation,structural bearing capacity,seis-mic measures,appearance quality,material strength,structure size and envelope system.The evalua-tion criteria are given according to standard specifications.Secondly,the G1 method and entropy weight method are used to determine the subjective and objective weights of indicators,and a cloud model for safety assessment of brick-concrete structure self-built house is constructed.Finally,the model is used to evaluate the safety of a brick-concrete structure self-built house in Luoping County,Yunnan Province,and the results are consistent with the actual evaluation results.The combination weighting cloud model can comprehensively evaluate the security of brick-concrete structure self-built house,providing reference for the safety identification and hidden trouble investigation of brick-con-crete structure self-built house in our country.
