【摘要】 钢管混凝土结构的应用前景越来越广阔,针对地震造成的钢管混凝土框架结构损伤,需要建立科学的评判方法。基于模糊数学理论,从构件损伤评判角度出发,以承重构件损伤、连接构件损伤、围护构件损伤为一级评价指标,框架柱、梁、板、填充墙、构件连接节点为二级评价指标,构件位移、裂缝、挠度、变形、松动、混凝土破坏度等外观损伤为三级评价指标,运用层次分析法确定评价因素的权重,并建立了模糊综合评价计算模型。研究表明,运用该模型可以定量计算震后钢管混凝土框架结构损伤程度。更多还原

【Abstract】 The application of concrete filled steel tubular(CFST) structure is more and more wide,scientific method of examination and evaluation of CFST column structure caused by earthquake are needed to be built up.Based on fuzzy mathematical theory,the paper builds the calculation mode of fuzzy comprehensive evaluation in the view of component damage,regarding load-bearing component damage,connecting component damage and enclosed component damage as first class evaluation indexes,frame columns,beams,plates,infilled walls and component connection nodes are taken as second class evaluation indexes and external damage of component displacements,cracks,girder deflection,deformation,loose,concrete damage level and so on are taken as third class evaluation indexes,analytic hierarchical process is used to confirm the weight of evaluation factors.The seismic damage of the frame structure of CFST is quantitatively calculated by applying this model.更多还原
