Research on Safety Risk Management of Steel Structure Building Construction Based on Game Theory-Cloud Model
Publication: ICCREM 2021
ABSTRACT
To identify the construction safety risks of steel structure buildings and accurately evaluate the construction safety risk level, a risk evaluation framework based on game theory-cloud model is proposed. This study adopts the fault-tree analysis method to comprehensively identify the factors affecting construction safety. Then, an evaluation index system is constructed using the 4M1E method. In addition, the analytic hierarchy process and the entropy method are combined to determine the subjective and objective weights of the indicators, respectively. Furthermore, the comprehensive weights of indicators are determined based on the cooperative game theory. Finally, the construction safety risk assessment model of steel structure residence is established through using the cloud model method. A steel structure project in Wuhan is selected for empirical analysis. The results of this proposed framework are basically consistent with the actual project. Therefore, this framework can provide a reference for the systematic safety management of steel structure construction.
