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 ...

Fatigue examination of reinforced-concrete bridge slabs using acoustic emission and strain monitoring data

Imane Bayane

The examination of bridges under service loading is key for understanding their condition and thus for their sustainable and efficient use. The need to extend the service duration of existing bridges is increasing, and therefore, efficient tools for examin ...

Model-Based Interpretation of Measurements for Fatigue Evaluation of Existing Reinforced Concrete Bridges

Ian Smith, Eugen Brühwiler, Sai Ganesh Sarvotham Pai, Imane Bayane

New methods are required for sustainable and economical management of bridges. Efficient management can be achieved by a detailed understanding of bridge behavior through monitoring and model-based data interpretation. This paper presents a methodology to ...

Investigation of fatigue damage in a RC deck slab due to moving loads through long-term monitoring of a road viaduct

Eugen Brühwiler, Imane Bayane

The behavior of reinforced-concrete structural elements under moving loads involves many complex parameters related to material properties, vehicle loading, environmental changes and structural response. It is difficult to generate the real conditions of l ...

Structural condition assessment of reinforced-concrete bridges based on acoustic emission and strain measurements

Eugen Brühwiler, Imane Bayane

A reliable novel monitoring approach is developed to assess the structural condition of reinforced-concrete bridge elements. The approach is based on combining acoustic emission technique and strain gauge measurements, and it is illustrated by a case study ...

Quantiﬁcation of traﬃc and temperature eﬀects on the fatigue safety of a reinforced-concrete bridge deck based on monitoring data

Eugen Brühwiler, Imane Bayane, Amol Mankar

For assessment of existing reinforced-concrete bridges, only few rules and recommendations are available, and engineers meanwhile apply design codes for new bridges to evaluate the fatigue safety of existing bridges leading to non-realistic approaches and ...

"Pocket-monitoring" for fatigue safety verification of a RC bridge deck slab

Eugen Brühwiler, Imane Bayane

The fatigue safety of the reinforced concrete (RC) deck slab of a sixty-year-old steel-concrete road viaduct is questioned based on the results of code-based "re-calculation". Since strengthening intervention would lead to major costs, detailed investigati ...

Acoustic emission and ultrasonic testing for fatigue damage detection in a RC bridge deck slab

Eugen Brühwiler, Imane Bayane

There is a significant need to examine precisely the conditions of concrete road bridges because of the increasing traffic and axle loads and the fact that most existing bridges were not designed with respect to fatigue. In-situ investigations are challeng ...

Quantification of the conditional value of SHM data for the fatigue safety evaluation of a road viaduct

Eugen Brühwiler, Imane Bayane

Fatigue safety verification of existing bridges that uses ‘‘re-calculation’’ based on codes, usually results in insufficient fatigue safety, triggering invasive interventions. Instead of “re-calculation”, Structural Health Monitoring (SHM) should be used f ...

Probabilistic reliability framework for assessment of concrete fatigue of existing RC bridge deck slabs using data from monitoring

Eugen Brühwiler, Imane Bayane, Amol Mankar

Assessment of existing bridge structures for inherent safety level or for lifetime extension purposes is often more challenging than designing new ones. With increasing magnitude and frequency of axle loads, reinforced concrete bridge decks are susceptible ...
