| Abstract: |
This paper presents the ambient vibration tests that were conducted on the Hawkshaw Bridge, a three-span cable-stayed bridge located in New Brunswick, Canada. Tri-axial wireless sensors were installed on the bridge girders to capture the bridge acceleration due to the normal traffic condition. Challenges that were faced during the tests and the post-processing of the data are discussed in this paper. The natural vibration frequencies were extracted using Operational Modal Analysis. The vibration frequencies were compared with the finite element analysis results of the original designed bridge and the discrepancies were discussed. |
