Condition assessment of concrete bridges during demolition

摘要

The research project ZEBRA lasting from 1997 to 2004 is a framework to gain knowledge from bridges in Switzerland that were demolished. These bridges enable a condition survey including destructive testing and non-destructive tests can be validated. Especially tendons can be accessed to inspect their actual state, which is almost impossible, if the bridge has to sustain its proper function. In total 89 bridges were recorded and 82 out of them were demolished. Detailed examinations were performed on 36 bridges.
