| Abstract: |
In order to improve the maintenance and management of the highway bridge deck, a test equipment was developed for grasping the rigidity of the deteriorated deck using the deformation of the deck obtained by the impact load. A soundness evaluation system of the bridge deck using the impact test result has been constructed, and this evaluation system utilizes the curvature of the neighbourhood of the load application point. The degradation degree was evaluated from the relationship between curvature and Young’s modulus calculated using deflection. When any abnormality is observed in the periodic inspection of the highway bridge deck, load bearing performance can be evaluated at an early stage by applying this system. |
