Application of AHP improved matter-element method in safety risk assessment of integral steel platform jacking formwork system
In China,super high-rise building construction technology has advanced significantly in recent years.Integral steel platform jacking formwork systems represent a high level in this field of construction technology and are frequently used in well-known projects.The AHP-improved matter element method was introduced because of the fuzziness and randomness of its construction.After conducting a field investigation on the construction site and having the project reviewed by an expert,a safety risk assessment model for the integral steel platformjacking formwork system was developed following the Code for Project Management of ConstructionEngineering(GB/T 50326-2017).First,the safety risk assessment indicator system's 19 indications are chosen after taking into account five factors,including personnel,equipment,environment,management,and technology;The weight of each index is calculated successively by using the analytic hierarchy process,including the weight of the index layer on the criterion layer and the weight of the criterion layer on the target layer.This safety risk assessment model of the integral steel platform jacking formwork system is based on the Analytic Hierarchy Process(AHP)-improved matter element method.The two vectors are multiplied to produce the overall weight of the index layer over the target layer;Create an assignment standard for each evaluation index,and then use the Delphi method to get the scoring tables for each evaluation index based on this standard.The safety risk level of the integral steel platform jacking formwork system is established following the maximization of membership.The gray correlation degree can be used to replace the European-style paste progress in calculating the gray correlation degree of each index for different evaluation grades.Finally,a super high-rise project is subjected to the safety risk assessment model based on the AHP-improved matter element method and the model's assessment outcomes are contrasted with the actual building condition.The findings demonstrate that the calculation outcomes of the assessment model are reasonable,dependable,and correct.It may serve as a benchmark for the safety control of super high-rise projects'integral steel platform jacking formwork systems.
