Abstract

This contribution describes a case-based decision support system which is intended for being used in the field of Structural Health Monitoring to support the assessment of structures (by using the example of lamp posts). Interpreting measuring data manually is a very complex task, time-consuming and influenced by the subjectivity of civil engineers. Therefore, the engineers shall be supported in assessing measuring data by using a case-based decision support system. A measurement of a structure and a manual assessment by an engineer represent a case in a case base. Similar cases/structures shall be retrieved and made available for assessing new measurements. For supporting the assessment of simple structures (lamp posts), a case-based system shall be provided for interpreting measuring data semi-automatically to make suggestions about lamp posts' condition. Thereby, time and costs can be reduced more than 90% by the use of computer-aided assessment in comparison with the manual interpretation.
