时变结构的模态参数识别是桥梁安全监测中的重要部分,近年来受到越来越多的关注,由于桥梁结构的动力特性相较于其他建筑有较大区别,为识别其在不同激励环境下的动态参数,以小钢梁为模型通过静载和动载的模拟试验,并通过软件对测得的数据进行对比分析,得到了合理的信号处理方案。 Modal parameter identification of time-varying structure is an important part of bridge safety monitoring, which has received more and more attention in recent years. Because the dynamic characteristics of bridge structure are greatly different from other buildings, Under the dynamic parameters of the small steel beam as the model through the static and dynamic load simulation test and the measured data by software comparative analysis of a reasonable signal processing program.
