Safety risk evaluation method for assembly building construction based on improved tractable cloud
In order to ensure the construction safety of assembled buildings,considering the ambiguity and randomness of the construction safety index factors,the combined empowerment-improved topological cloud model is used to evaluate the construction safety risk.Firstly,the evaluation index system is constructed from the perspective of"three-degree space"in the physical,social and information levels;secondly,the subjective and objective weights are determined by the improved hierarchical analysis method(AHP)and entropy weighting method(EW),and the comprehensive weights are determined based on the distance function,and a method of determining the entropy of the cloud is proposed according to the cloud theory and the theory of topology,and propose a cloud entropy determination method and improve the traditional topological cloud model,and construct the evaluation model;finally,the model is applied to the engineering example and compared with other models.The results show that the evaluation grade of the construction project is very safe and has high credibility;the reliability and feasibility of the model are verified,providing a more scientific and accurate evaluation method for the safety risk evaluation of assembly building construction.
