摘要
基于脉动试验和有限元分析对某公路桥梁进行了健康状况评估。基于ANSYS对该桥梁的新、旧桥进行了有限元模态分析,得出了其横竖向前两阶频率。通过脉动试验,得出了新、旧桥的横竖向前两阶测试频率。经过比较可以看出桥梁的刚度和整体性有所加强,动力性能较好。
The health condition evaluation of a highway bridge was carried out based on an ambient test and finite element analysis. Firstly, the finite element modal analysis of the new and old bridges was performed based on ANSYS, and the first two order frequencies were extracted. Secondly, the first two order experimental frequencies were identified based on an ambient test. The comparison shows that the rigidness and integrity of the bridge are strengthened and the dynamic performance is better.
