为了提高有限元模型修正技术的建模精度,从模型修正的对象、信息来源和其他方法3种分类方法出发,系统阐述各种有限元模型修正方法的原理,梳理各种方法的脉络关系及技术演变;从理论研究和桥梁健康监测应用2个方面,分析各种方法的应用现状及其优缺点.研究结果表明:有限元模型修正研究发展的7大方向为:①多尺度、分散子结构、代理模型、随机、非参数的模型修正方法;②基于强度理论及非线性理论的模型修正方法;③通用的模型修正算法和统一的评价准则;④数值模拟、理论分析和工程应用相结合;⑤充分利用桥梁工程特有的全过程信息;⑥开发针对桥梁结构的模型修正软件;⑦有限元模型确认.
Present research status and development trend of finite element model updating based on bridge health monitoring
In order to improve modeling accuracy of finite element model updating technology,this paper systematically discussed the principle of various methods of finite element model updating according to three classification methods,including object-based model updating method,information-source-based model updating method and another method,and sorted out the context of their relationships and the technology evolution of various model updating method.It also analyzed the application status of various methods and their advantages and disadvantages in two aspects including theoretical research and bridge health monitoring applications.The results show that there are 7 further research fields of the finite element model updating technology:① multiscale,isolated substructure,agent models,stochastic and nonparametric model updating method; ② the model updating method based on strength theory and nonlinear theory; ③ general model updating algorithm and unified evaluation criteria; ④ the model updating method combining numerical simulation,theoretical analysis and application in engineering; ⑤ making full use of the whole-process information which is unique to bridge engineering; ⑥ developing software for model updating of bridge structure; ⑦ finite element model validation.3 figs,70 refs.
