A Quantized Control Model for Safety Management of Repair of Collapsed Walls of High-Rise Buildings

To ensure safety during the process of repairing of collapsed walls of the high-rise buildings after an earthquake, some safety management guidance measures are given. In addition, a safety management method for repair of collapsed walls of high-rise buildings after an earthquake was proposed. Combined with principal component analysis and information entropy method, the controlled characteristic variables for the repair of collapsed wall of high-rise buildings post earthquake were extracted to determine the weight of the model evaluation index. The quantized control for the management of collapsed wall restoration based on weighted learning method was conducted. A security management control model was constructed by constrained parametric analysis through grayscale quantitative evaluation. The construction safety management control was realized by adopting the fuzzy scheduling algorithm and the optimization decision was completed. The management benefit and cumulative evaluation percentage for the restoration construction management control for the collapsed wall were verified via simulation experiments. The case analysis results showed that the management benefit of this method can reach 95.34%, and the cumulative evaluation percentage was about 98.65%. The method can considerably improve the safety management efficiency of the construction process and ensure construction safety.
