| Abstract: | In this paper, the strength and stiffness of the structural bridge have been investigated based on the dynamic load testing of the prestressed concrete T-beam in expressway overpass bridge. We tested the bridge parameters of natural frequency, damping ratio, impact factor, etc. The results would provide a solution for bridge performance evaluation and guide the operations during maintenance and repairment. |
