Lantsoght, E.O.L. (author), van der Veen, C. (author), Hordijk, D.A. (author), de Boer, A. (author)As the bridge stock in the Netherlands and Europe is ageing, various methods to analyze existing bridges are being studied. Proof load testing of bridges is an option to experimentally demonstrate that a given bridge can carry the prescribed live loads. Based on extensive research on proof load testing of reinforced concrete slab bridges carried...journal article 2017

(author)Proof load testing can be a suitable method to show that a bridge can carry the required loads from the code without distress. This paper addresses the preparation, execution, and analysis of a proof load test on a four-span reinforced concrete solid slab bridge, viaduct de Beek. The bridge has one lane in each direction, but was restricted to a...conference paper 2017

Lantsoght, E.O.L. (author), Koekkoek, R.T. (author), van der Veen, C. (author), Hordijk, D.A. (author), de Boer, A. (author)For existing bridges, proof-load testing can be a suitable assessment method. This paper addresses the evaluation of a posted reinforced concrete slab bridge over a highway through proof-load testing, detailing the preparation, execution, and analysis of the test. As the target proof-load and the required measurements for proof-load testing...journal article 2017

de Boer, J.S. (author)This paper is a partial review of the literature on ‘social preferences’. There are empirical findings that convincingly demonstrate the existence of social preferences, but there are also studies that indicate their fragility. So how robust are social preferences, and how exactly are they context dependent? One of the most promising insights...journal article 2017

Ghafaryasl, B. (author), Baart, Robert (author), de Boer, J.F. (author), Vermeer, K.A. (author), van Vliet, L.J. (author)Optical coherence tomography (OCT) yields high-resolution, three-dimensional images of the retina. A better understanding of retinal nerve fiber bundle (RNFB) trajectories in combination with visual field data may be used for future diagnosis and monitoring of glaucoma. However, manual tracing of these bundles is a tedious task. In this work,...conference paper 2017

Verhagen, W.J.C. (author), Curran, R. (author), de Boer, L.W.M. (author)Costs associated with unscheduled and preventive maintenance can contribute significantly to an airline's expenditure. Reliability analysis can help to identify and plan for maintenance events. Reliability analysis in industry is often limited to statistically based approaches that incorporate failure times as...conference paper 2017

Lantsoght, E.O.L. (author), van der Veen, C. (author), de Boer, A. (author)Proof loading of existing bridges is an option to study the capacity when crucial information about the structure is lacking. To define the loading criteria for proof load testing, a review of the literature has been made, finite element models of existing viaducts have been made, and on these viaducts, proof loading tests have been carried out....conference paper 2017

Lantsoght, E.O.L. (author), van der Veen, C. (author), de Boer, A. (author)Most methods for the design and analysis of reinforced concrete slabs for punching are based on experiments on slab-column connections, reflecting the situation in building slabs. Slab-column connections with unbalanced<br/>moments have also been studied in the past. Experiments indicate that the accuracy of models for asymmetrically loaded...conference paper 2017

De Witt, A. (author), de Boer, Joop (author), Hedlund, Nicholas (author), Osseweijer, P. (author)For addressing climate change, public support for changes in policy is needed, as well changes in individual lifestyles. Both of these appear to be intimately related with people's worldviews. Understanding these worldviews is therefore essential. In order to research and 'map' them, we translated the theoretical 'Integrative Worldview...journal article 2016

Several recent studies emphasize the potential role of ecosystems in flood protection as adaptive risk reduction measures while also contributing to carbon fixation. Here, we...journal article 2016

Lantsoght, E.O.L. (author), van der Veen, C. (author), de Boer, A (author)In August 2014, the Ruytenschildt Bridge, a reinforced concrete solid slab bridge, in Friesland, the Netherlands was tested until failure. One of the goals of the experiment is to analyze the failure mode of the slab bridge under a tandem of 4 wheel loads and to compare the capacity of the full bridge structure to the predicted results, to have...conference paper 2016
