桥梁动力学计算模型的修正及灵敏度

Bridge structural dynamic model calibration and the sensitivity analysis

介绍了桥梁动力学计算模型的修正及灵敏度分析的基本理论,并对一座预应力混凝土连续刚构箱梁桥进行了动力学灵敏度的分析及修正,并与现场试验结果进行比较,得出相关结论。

In this paper, the basic theory of the bridge structural dynamic model calibration and the sensitivity analysis is introduced, and for a prestressed continuous rigid frame bridge dynamic model, the structural model calibration and the sensitivity analysis was conducted： Finally, the latest model analyzing results were compared with the dynamic testing results.
