Abstrakt: |
Because many infrastructures such as bridges will entrance their last stage of designed durability in Japan, it becomes much more important to judge whether replace them or use them continously over their designed durability while doing maintenance. An old bridge should be inspected much exactly by expert engineers rather than at its initial stage of lifetime. Now, the structural health monitoring (SHM) technique makes it possible to gather more and more useful data to investigate dameges.Whether inspection by expert engineers or SHM, the cost problems for sustainable bridge maintenance should be solved first. In this paper, a concept of detecting damage signs in long-term service bridges using acceleration response of running bus on the bridges. The conclusions of this paper will give good references to develop a creative useful method for sustainable bridge maintenance. |
