Structural identification methods for full-scale bridges

Ian Smith, James-Alexandre Goulet, Irwanda Laory

Results of two doctoral theses, one using a model-based approach and the other using model-free methods, are summarized. Both included case studies of full-scale bridges. While model-based approaches are appropriate for individual infrastructure-management ...

Reducing Uncertainties Regarding Remaining Lives of Structures Using Computer-aided Data Interpretation

Ian Smith, James-Alexandre Goulet, Romain Pasquier

The growing importance of economic and environmental issues associated with the replacement of transportation infrastructure creates a demand for new techniques that are able to predict accurately the behaviour of existing structures. While monitoring stru ...

Probabilistic Model Falsification for Infrastructure Diagnosis

James-Alexandre Goulet

Most infrastructure in the western world was built in the second half of the 20th century. Transportation structures, water distribution networks and energy production systems are now aging and this leads to safety and serviceability issues. In situations ...

Extended Uniform Distribution Accounting for Uncertainty of Uncertainty

Ian Smith, James-Alexandre Goulet

Increasingly, uncertainties are explicitly considered for important engineering tasks. Often, little case-specific information is available for characterizing these uncertainties. Uniform distributions are an easy way to describe errors in absence of more ...

Overcoming the limitations of traditional model-updating approaches

Ian Smith, James-Alexandre Goulet

Model updating is useful for improving structural performance assessments. This paper examines an important assumption of traditional model-updating approaches. This assumption requires the error independence between points where predictions and measuremen ...

Multimodel Structural Performance Monitoring

Ian Smith, James-Alexandre Goulet

Measurements from load tests may lead to numerical models that better reflect structural behavior. This kind of system identification is not straightforward due to important uncertainties in measurement and models. Moreover, since system identification is ...

Estimation of modelling errors in structural system identification

Ian Smith, James-Alexandre Goulet

This paper presents a method for measurement-system design through criteria related to model based structural identification. Using a multi-model approach and results from previous research carried out at EPFL, an improved algorithm is proposed. The algori ...

Structural identification to improve bridge management

Ian Smith, James-Alexandre Goulet

This paper presents results from static loads tests performed on the new Langensand Bridge built in Switzerland. A systematic study of over 1000 models subjected to three load cases identifies a set of 11 candidate models through static measurements. Predi ...
