Abstract
To improve the reliability of an inspection of civil structures, the expectation for health monitoring of a structure is growing. To develop a practical health monitoring system, it is necessary to build the system in which not only development of evaluation method but implementable sensor system which include AD converter. However, a monitoring system is developed on a seeds basis in many cases, it is difficult for sensor maker to grasp sensor spec the user expects. In this paper, for development of monitoring system, the required item was arranged and the feature of evaluation criteria was arranged using the actual monitoring data measured by the bridge pier of the railway bridge. Moreover, the example of specification was shown about accuracy or durability in terms of external force to assume or evaluation index. Reliable systems development is expected by the high added value with which the user and the maker were united for develop monitoring system.
