基于层次分析法的既有建筑结构加固方案设计研究

The research on existing buildings strengthening sche me with analytic hierarchy process

通过研究既有建筑加固设计的优化方向和层次分析法的创新进展,以建立层次结构模型的基础上,综合考虑建筑物安全性、造价、环境影响和施工工期四个方面。结合工程实例,建立了既有结构加固设计方案比选分析模型,利用1~9标度法对提出方案的主要因素进行比较,构建层次判断矩阵,最终确定最优方案,为既有建筑加固方案优化设计提供理论依据。

Depending on opti mization direction of existing bulidings reinforce ment design,with the innovation progress of analytic hierarchy process.On the basis of establishing the hierarchical structure model,we consider co mprehensively the safety,cost,environ mental impact and construction period.The main factors of the project case are co mpared by the 1-9 scale method and the level judg ment matrix is established.The level judg ment matrix is sorted totally and singly by calculating.The agree ment of calculated results is verified.Further more,the best plan is deter mined by calculating the weight value and sort disadvantages of each layer in the total target layer,which provide a theoretical basis for opti mal design of existing buildings reinforce ment sche me.
