A global framework for data-informed bridge examination
Eugen Brühwiler, Numa Joy Bertola, Philippe Schiltz
Examining the performance of an existing bridge requires information on several aspects, such as design choices, material properties, and ongoing degradation processes. It often happens that some critical information is not available. The traditional appro ...
2024Influence of model uncertainty and long term deformations in action effects calculation in reinforced concrete structures
Most codes of practice adopt a semi probabilistic design approach for the dimensioning and assessment of structures. Accordingly, structural safety is ensured by performing limit state verifications using design values determined with adequately calibrated ...
EPFL2024Framework to evaluate the value of monitoring-technique information for structural performance monitoring
Eugen Brühwiler, Numa Joy Bertola
The management of existing civil infrastructure is becoming more crucial as a large share of bridges is approaching their theoretical end of service duration. Structural performance monitoring aims to verify bridge safety at a given time, and it should be ...
2023Selection of informative monitoring techniques for bridge-performance evaluations
Eugen Brühwiler, Numa Joy Bertola
Decisions regarding the management of civil infrastructure are becoming more crucial as a large share of bridges is presently approaching what is often considered to be the end of their theoretical service duration. Evaluating existing structures using a d ...
Trinity College2023Vortex shedding from a composite hydrofoil: Experimental evidence of a novel "partial lock-in"
Mohamed Farhat, Thomas Antoine Nicolas Berger, Qin Wu, Yunqing Liu
Lock-in is of great importance in many engineering applications due to its practical implications for structural safety. The influence of composite bend-twist coupling on the wake dynamics and vortex-induced vibration around a carbon fiber composite hydrof ...
Melville2023Sensing the structural behavior: A perspective on the usefulness of monitoring information for bridge examination
Eugen Brühwiler, Numa Joy Bertola, Yves Sylvain Gilles Reuland
Managing existing civil infrastructure is challenging due to evolving functional requirements, material aging, and climate change. With increasingly limited economic, environmental, and material resources, more sustainable solutions for practical asset man ...
2023Reliability analysis and partial safety format calibration considering the characteristics of the resistance of reinforced concrete structures
Every engineering calculation is an approximation of reality, with inevitable uncertainties involved. This fact implies that a reliability verification accounting for the uncertainties is a necessary step in the design and assessment of structures. Nowaday ...
EPFL2023Swiss dams: Overview of historical development
With more than 220 large dams in operation, compared to its surface of some 41ʹ000 km2, Switzerland has a very large fleet. They were erected to meet various economic and protection needs. Their main assignments concern the storage of water for later use, ...
CRC Press/Balkema2023Bridge enhancement by means of the UHPFRC Technology: concepts and applications
Existing bridges in reinforced concrete (RC) need to be enhanced in order to comply with utilization and safety requirements of future use, in particular for higher traffic loads. Such enhancements comprise strengthening to increase the structural resistan ...
Taylor & Francis2021Enhancement of riveted steel bridges by adding a trough in UHPFRC acting in composite action
Riveted railway bridges are commonly considered as being “old”, having fatigue damage and are therefore replaced. While this practice should be by now obsolete by using novel engineering methods like structural monitoring, prolongation of the service durat ...
