| 摘 要： | 结构参数识别是结构抗震安全性能鉴定和健康诊断的基础，利用地震观测记录来识别结构模态参数，是地震工程领域备受关注的研究课题之一。本文利用实际结构的地震观测记录，对一维、多维和整体ARX模型三种模态参数识别方法进行了对比分析。结果表明：整体ARX模型对多自由度结构的模态参数识别较为稳定且精度较高；实际应用中多维ARX模型有时会导致丢失模态和虚假模态现象。

| Abstract: | Structural parameter identification is the basis of safety assessment for earthquake-resistance and health diagnosis of structures.Structural modal parameter identification using seismic observation records receives full attention in earthquake engineering.In this paper,modal parameter identification methods of one-dimensional,multi-dimensional and integral ARX models are compared and analyzed by using actual seismic observation records of buildings.The results show that integral ARX model gets stable and h... |
