摘要
文章介绍了一种基于监测数据的结构状态评估及安全诊断方法,建立了对自动化监测设备获取的海量监测数据的清洗及趋势提取算法,包括采用拉依达准则对异常突变值的处理,以及采用平台宽度阈值控制方法对异常恒定值的处理.在综合考虑不同指标和不同测点数据后,构建了基于复相关系数赋权的半经验半理论的综合结构状态评估模型.根据状态评估曲线与安全阈值之间的相互关系,最终提出了基于分级预警的结构安全诊断方法.
Abstract
A method of structural state assessment and safety diagnosis based on monitoring data was proposed.The algo-rithm of cleaning and trend extraction of massive monitoring data obtained by automatic monitoring equipment was estab-lished,including the processing of abnormal abrupt value by using the Laida Criterion and the processing of abnormal con-stant value by using the platform width threshold control method.After considering the data of different indexes and meas-uring points comprehensively,a semi-empirical and semi-theoretical comprehensive structural state evaluation model based on multiple correlation coefficients was constructed.According to the relationship between the state assessment curve and the safety threshold,the structure safety diagnosis method based on hierarchical early warning was proposed.
