This study is devoted to optimizing the reinforcement and renovation scheme of steel frame-concrete cylinder structure to enhance its safety performance and improve the quality of reinforcement engineering.Firstly,the paper evaluates the necessity of reinforcement through the structural function function,and then selects the Yongding Building fire protection and structural safety repair project as a case to carry out a comprehensive structural investigation.Based on the survey results,a cost-effectiveness model is constructed and a set of evaluation index system is developed.The TOPSIS method is used to evaluate the different reinforcement schemes comprehensively,and the optimal reinforcement scheme is finally determined.The scheme not only has obvious advantages in terms of economy,construction period and later maintenance cost,but also verifies its remarkable effect in improving structural safety and overall quality through finite element analysis.The research results confirm that the evaluation and optimization method established in this study can quickly and effectively select the optimal reinforcement scheme,reduce the construction cost,shorten the construction period,and ensure the effectiveness and safety of the reinforcement project.Looking forward to the future,the research will continue to explore more new reinforcement technologies and more advanced optimization methods to meet the growing engineering needs and further improve the scientific and practical nature of reinforcement and renovation projects.
