大型装配式建筑结构耐久性失效风险分析

Analysis of risk of durability failure of large assembled building structures

简要介绍了层次分析法的原理与运用方式、步骤,在此基础上,提出一套针对装配式建筑开展耐久性失效风险评价和计算的研究方法。以某装配式地下建筑结构为例,应用层次分析法,对影响其耐久性风险的各个因素进行分级排序,并探讨这些因素对结构耐久性失效风险的影响程度,进而取得该结构耐久性失效风险分析的量化指标。该方法可为装配式建筑工程项目决策及降低风险、提高耐久性能并进而采取相应的防治措施提供参考依据。

This paper introduces the principle,using method and steps of analytic hierarchy process.On this basis,a set of research methods for evaluating and calculating durability failure risk are proposed.Then,taking an assembled underground structure as an example,the risk factors are classified and sorted by using the analytic hierarchy process,and the influence degree of the main factors on the durability failure risk is discussed,and the quantitative index of the durability failure risk analysis of the structure is obtained.The research methods proposed in this paper can provide reference for decision-making of assembly construction projects,risk reduction,durability improvement and corresponding preventive measures.
