摘要
基于可靠度理论,在对现役钢闸门结构荷载及抗力统计分析的基础上,采用JC法对现役平面钢闸门基本构件的时变可靠指标进行了计算和分析.在此基础上,采用层次分析法对现役平面钢闸门动态可靠度进行了评估,并用算例进行了说明.结果可供制定现役钢闸门结构可靠性鉴定标准时参考或使用.
Based on reliability theory,and on the basis of analysis of loads and resistance for existing steel gate structures,the JC method was adopted for calibrating and analyzing time variant reliability index of existing steel gate structural members.Based on them,the dynamic reliability assessment of plane steel gate structures was analyzed by applying the analytical hierarchy process method,and furthermore a numerical example was adopted for illustrating the method.These research achievements can serve as a reference for establishment of reliability standard of existing steel gate structures.
