Building assembly safety assessment based on the ISM structural model

现代装配式建筑吊装的安全性评估具有重要意义,有利于降低事故风险。为了实现现代装配式建筑吊装的安全性评估,研究引入了解释结构模型与决策试验和评价实验法相融合的评估方案,构建20个安全影响因素,采用毕达哥拉斯模糊集与层次分析法-最优解法对其进行评估。结果表明:安全措施投入与使用情况的中心度高达2.49,重要性最高。安全标准政策环境的中心度最低仅为1.12,重要性最低。安全应急方案的原因度高达0.75,影响力最高。D3工种搭配协调度的原因度最低,仅为-1.24,其受其他因素的影响作用最高。经过对相关案例的深入分析,发现研究所提方法的应用结果与实际情况高度一致,充分证明了该方法在实际应用中的可行性。

At present,the safety assessment of the hoisting of modern prefabricated buildings is a complex and important issue.We have developed an evaluation scheme that includes decision experiments,evaluation experiments,and deconstructive structural models,and the study constructed 20 safety influencing factors and evaluated them using Pythagorean fuzzy sets and Analytic Hierarchy Process-Optimal Solution.The results indicate that the centrality of the investment and use of safety measures is as high as 2.49,with the highest importance.The centrality of the safety standard policy environment is the lowest at only 1.12,with the lowest importance.The reason for the safety emergency plan is as high as 0.75,with the highest impact.The reason for the coordination of D3 job types is the lowest,only-1.24,and it is most affected by other factors.After in-depth analysis of relevant cases,it was found that the application results of the proposed method are highly consistent with the actual situation,which fully proves the feasibility of the method in practical application.The research provides effective risk control strategies and decision support for practical engineering.
