Schadensidentifikation mit modalen Parametern: Anwendung auf extern vorgespannte Hohlkastenbrücken

By: Material type: ArticleArticleLanguage: German Publication details: KIT Scientific Publishing 2016Description: 1 electronic resource (IX, 152 p. p.)ISBN:
  • KSP/1000051045

Subject(s): Online resources: Summary: With a focus on the monitoring of concrete bridges, this study evaluates 19 different methods under realistic constraints. Then, the detailed numerical model of an unbonded post-tensioned box-girder bridge is created. There, nonlinear material laws, which have been validated by laboratory tests, are applied. Combining six different methods, the increase in cracking as a consequence of either the settlement of the pier or the decrease in the tension force can be assessed and localized.
