Applied Bayesian pre-posterior and life-cycle cost analyses for determining and optimizing the value of structural health monitoring for concrete structures Ghent University
“How safe are our bridges?”Although a lot of research on structural safety has been performed during the last decades, answering this question for existing structures is still a challenging problem engineers are increasingly confronted with. This is mainly because a proper framework for assessing the safety of ageing or even deteriorated structures that can properly take into account the results from inspections and monitoring is still ...
Multi-layer Bayesian life-cycle methodology for the structural assessment of existing concrete structures (lifeMACS) KU Leuven
Repair and upgrading of structures are becoming increasingly important and are associated to an increasing part of activities in the construction sector. Current state of the art lacks a coupled Bayesian framework that enables to update through-life performance predictions, optimize inspections and interventions and fully exploit knowledge available through information gathered or modelled, limiting the exploitation of the benefits of ...

Probabilistic formulation of the structural reliability of concrete structures subjected to fire in relation to risk-based desicion making and risk-transfer mechanisms Ghent University
A full-probabilistic methodology for calculating the safety level of concrete structures during and after fire will be developed, using numerical simulations. This enables to compare design or repair alternatives and assess the safety of existing concrete structures. Decision making strategies will be developed for cost optimization of structural design or strenthening alternatives. The responsibilities of different stakeholders and the ...
Applied Bayesian Pre-Posterior and Life-Cycle Cost Analysis for Determining and Optimizing the Value of Structural Health Monitoring for Concrete Structures KU Leuven
The general aim of this research is to develop a methodology for rational decision making in the management of existing structures, so that the limited resources for the management of infrastructure can be optimally deployed. A life-cycle perspective will be adopted, allowing decisions on strategies for inspection, monitoring and strengthening. Relevant uncertainties, which are unavoidable in the condition assessment of existing structures as ...
The Structural Behaviour of Corroded Reinforced Concrete Beams: Experimental and Numerical Studies for the Assessment of Corrosion-damaged Reinforced Concrete Beams KU Leuven
Assessing the structural performance of reinforced concrete (RC) structures damaged by chloride-induced corrosion is an important research topic with a high societal impact. Different models exist in the literature to predict the flexural capacity of corroded RC beams. These models incorporate corrosion damage according to damage relations calibrated on a specific set of data. The variety of approaches and relations in incorporating pitting ...
A coupled local-global structural health monitoring approach for assessing the structural performance of deteriorated concrete components with reinforcement corrosion. KU Leuven
Worldwide, many civil engineering structures reach the end of their designed lifetime. Reassessing their design lifetime or performance for altered load conditions, raises questions on their remaining capacity. This doctoral research aims at developing a local-global structural health monitoring approach for assessing the performance of reinforced concrete components subjected to degradation, in particular corrosion of the reinforcing steel. ...
Structural safety, durability and robustness of complex concrete discontinuity regions under uncertainties Ghent University
The safety, durability and robustness of concrete structures largely depends on the ability to accurately predict their (time-dependent) structural response for which the development of appropriate modelling techniques is of paramount importance. However, in concrete discontinuity regions such as deep beams, half joints, corbels, nodes, etc., the strain distribution is significantly non-linear. Hence, for design and assessment typically limit ...
