震后钢筋混凝土单层工业厂房的快速鉴定方法
|
摘要
目前我国没有专门针对于钢筋混凝土单层工业厂房震后快速鉴定的标准或规范,也没有成熟的震后快速鉴定方法。在大量分析单层工业厂房震害基础的前提下,基于层次分析法,提出一种应用于震后单层工业长房安全性快速评估的方法。该方法在分析单层工业厂房常见震害的基础上,对地震中构件的破坏程度提出了定量和定性的判断标准;利用模糊数学方法对各类构件进行安全等级评价,形成隶属度判断矩阵;采用层次分析法对各类构件、各结构层进行权重评价;依据等级隶属度判断矩阵和各类构件、各结构层的权重进行综合分析,得出整体结构的安全性评价。建议的方法简单易行,层次清晰,鉴定结果较为合理。可对震后紧急情况下应急救援政策的制定、救灾措施的实施和开展提供科学的决策依据。
Currently,there is no code and mature method that are specially used for the rapid identification of the reinforce concrete single-factory building after the earthquake in China.A specific method used for rapid assessment of the single-factory building after the earthquake is advised in this paper.Based on the analysis of earthquake damages of single-factory building,this method gives quantitative and qualitative judgments to the damage extent of the common components in the earthquake.By using the fuzzy mathematics method,the security level of the components can be evaluated and judgment matrix of membership grade can be established.Then the weights of components and structures are evaluated by using the AHP.Finally,according to analyzing the judgment matrix of level membership grade and the weights of components and structures comprehensively,the safety evaluation of the whole structure can be acquired.This method is easy to apply and has clear layers.The identification result of this method is accurate.In accordance with this method a computer program can be easily compiled to make the identification work procedurally and reduce the workload and identification time.Besides,by using this method,the judgment reference can be provided to set down the policies of salvation and put the rescue measures into practice.
