摘要
模态识别是结构健康监测教学中的重要环节。依托某地下建筑工程实验室多年健康监测研究成果及设备环境条件,在传统理论教学模式上,将DHDAS软件及其所涉及的分析方法与应用工具引入研究生模态识别课程。以“混凝土简支桥梁模态识别方案设计”为主题,构建了课堂讲解-现场演示-模拟操作-数据处理的多元化教学模式,并通过现场试验进一步论证了该模式的实用性。结果表明,学生通过课程学习掌握了DHDAS软件在模态识别中的相关分析方法与应用技能,达到了设计实践与理论支撑相结合的目的。
Modal identification is an important part in the teaching of structural health monitoring.Relying on the research background and conditions of the structural health monitoring of key laboratory of military underground architectural engineering,DHDAS software and its related analysis methods and tools are introduced into graduate modal identification courses.The courses focus on“modal identification scheme design in concrete simply supported bridge”,and a diversified teaching mode of“classroom explanation-live demonstration-simulation operation-data processing”is developed,the practicability of the design scheme derived by this method is further demonstrated through relevant evaluation experiments.Through learning on the course,students can master relevant analysis methods and tools in DHDAS software and combine design practice with theories,which has important realistic meaning in training applied innovative spirit and practice ability of graduate student,laying a foundation for independent research in the later stage.
