Yang, Y. (author), Hordijk, D.A. (author), de Boer, A. (author)This paper presents the Acoustic Emission (AE) measurement of several tests carried out on reinforced concrete beams sawn from a 50 years old concrete bridge – Ruytenschildt bridge. The purpose of these tests is to provide additional information to the already executed in-situ load testing on the bridge. In addition to the AE measurement...conference paper 2016

(author), Zuurbier, Coert (author)Objective and design: We examined the role of IL-6 in the temporal development of cardiac ischemia–reperfusion injury employing a closed-chest I/R model. Materials/methods: Infarction, local and systemic inflammation, neutrophil infiltration, coagulation and ST elevation/resolution were compared between wild-type (WT) and IL-6-deficient (IL-6...journal article 2016

Lantsoght, E.O.L. (author), van der Veen, C. (author), de Boer, A (author), Walraven, J.C. (author)Reinforced concrete short-span solid-slab bridges are used to compare Dutch and North American practices. As an assessment of existing solid-slab bridges in the Netherlands showed that the shear capacity is often governing, this paper provides a comparison between Aashto (American Association of State Highway and Transportation Officials)...journal article 2016

Lantsoght, E.O.L. (author), van der Veen, C. (author), de Boer, A (author), Hordijk, D.A. (author)A large number of existing reinforced concrete solid slab bridges in the Netherlands are found to be insufficient for shear upon assessment. However, research has shown additional sources of capacity in slab bridges, increasing their total capacity and possibly changing their failure mode. Previous testing was limited to half-scale slab...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

Lantsoght, E.O.L. (author), van der Veen, C. (author), Walraven, J.C. (author), de Boer, A. (author)A 55-year-old bridge showed large cracking in the approach bridge caused by restraint of deformation and support settlement. After repair, it was uncertain at which crack width the traffic loads on the bridge should be further restricted. The shear capacity was calculated by counting on the aggregate interlock capacity of a supposedly fully...journal article 2016

de Boer, G.J. (author), Baart, F. (author), Jagers, B (author), Becker, B.P.J. (author)Assessment of environmental status and integral safety requires combination of information from many sources, coming from either databases or increasingly via live model (scenario) simulations. Many of these models require input from one another, sometimes unidirectional, but more and more two-directional as well. Many protocols and frameworks...conference paper 2014
