Sensitivity Analysis for Deteriorating Bridges using Bus Acceleration Sensors

摘要

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