| 要旨 |
Structural evaluation of existing infrastructures becomes necessary due to deterioration, change in service, incresed loading and damages due to natural disasters such as earthquakers and fires. In this paper, we present the use of fuzzy set theory for assessing the overall structural rating of highway bridges. Fuzzy sets are used to express the lack of precision in field observations. The system combines the experience and judgement of investigating engineer, results of field observations and if needed strength computation for individual members. A fictitious example of a simple RC highway bridge is presented.
