Over view

WG3, in conjunction with the WG1 and WG2, performs loading tests on testing girders and removal girders which have suffered both salt damage and ASR degradation. By using relationship between the testing data, the result of nondestructive inspection and the usability, the loading capacity, it is hoped to establish effective inspection items and the nondestructive inspection technology. In addition, it is possible to utilize these knowledge to develop a long term monitoring system on actual bridges effected by salt damage and ASR degradation.

①Investigation of exiting conditions according to static and vibration experiments on degradation bridges
②Developing the monitoring system that can grasp the change of degradation bridges
③Estimating the cause of deterioration, the serviceability and the loading capacity based on the variation of vibration characteristics of bridges
④Experimental validation of serviceability and loading capacity according to loading test and vibration monitoring on removal girders and testing girders subjected to salt damage and ASR deterioration.
⑤Long term monitoring on bridges suffered early deterioration
⑥Proposal of a maintenance management system of the bridges using the real-time long term monitoring
