Cost-benefit evaluation of a monitoring system for structural identification of existing bridges

Eugen Brühwiler, Numa Joy Bertola, Imane Bayane

The monitoring of existing infrastructure has the potential to improve structural-condition assessment, leading to better asset management. Monitoring data, collected through load testing, help identify unknown model-parameter values, and this model-updati ...

Decision Framework to Balance Environmental, Technical, Logistical, and Economic Criteria When Designing Structures With Reused Components

Corentin Jean Dominique Fivet, Numa Joy Bertola, Jan Friedrich Georg Brütting, Célia Marine Küpfer

The reuse of structural components in new buildings has great potential to reduce the environmental impacts of the construction sector but remains uncommon practice. An obstacle to its wider implementation is the lack of robust assessment methods and decis ...

Combining monitoring information and UHPFRC strengthening to extend bridge service duration

Eugen Brühwiler, Numa Joy Bertola

As many bridges are approaching the end of their supposedly theoretical service duration, finding novel technical solutions to extend their service duration is crucial, also for reasons of sustainability. In this article, two strategies (structural perform ...
