Vargas, Daniel (author), Lantsoght, E.O.L. (author), Genikomsou, Aikaterini S. (author)Eccentric punching shear can occur in concrete slab–column connections when the connection is subjected to shear and unbalanced moments. Unbalanced moments occur in all floor slabs at the edge and corner columns. As such, this problem is of practical relevance. However, most punching experiments in the literature deal with concentric punching...journal article 2022

Walraven, J.C. (author), Droogné, Didier (author), Grunewald, S. (author), Taerwe, Luc (author), Cotovanu, Bogdan (author), Rovers, John (author)An investigation is carried out into the applicability of self-compacting high-performance fiber concrete (HPFC) in foundations. A concrete mixture has been designed with a concrete cube strength of about 110 MPa. The concrete contains 60 kg/m<sup>3</sup> steel fibers. The properties of the HPFC developed are very suitable for structural...journal article 2021

Sous, D. (author), Dodet, G. (author), Bouchette, Frédéric (author), Tissier, M.F.S. (author)This paper reports on a combined experimental and numerical study dedicated to barrier reefs hydrodynamics. A network of pressure sensors and velocity profilers has been deployed for more than 2 months over the Ouano reef barrier, New Caledonia. The primary aim of the study is to assess the relevance of the classical depth-averaged momentum...journal article 2020

Duinmeijer, S.P.A. (author), Oldenziel, G. (author), Clemens, F.H.L.R. (author)In order to analyse the flow characteristics of free-surface vortexes and to validate the Burgers vortex model by using stereo particle image velocimetry, experiments are conducted in a 600 mm diameter vortex tank. Measured axial velocities indicate that 10–25% of the flow is transported through the vortex core. The velocity profiles show that...journal article 2020

Pol, J.C. (author), van Beek, Vera (author), Kanning, W. (author), Jonkman, Sebastiaan N. (author)Backward erosion piping is an important failure mode of dikes and dams. The time required for the backward erosion process to result in dike failure is expected to be an important factor in the safety of dikes. This holds especially in coastal and estuarine areas which are dominated by storm surge, and pipes may not fully develop during a storm....conference paper 2019

den Hartog, Harry (author)Countless waterways defined both the rural and urban landscape and related daily life activities in China’s Yangtze River Delta for many centuries. However, much of these bodies of water disappeared due to extremely rapid urbanization in the last three decades and this process is ongoing. This paper critically assesses how the appreciation and...journal article 2019

Winter, Casper de (author), Palleti, Venkata Reddy (author), Worm, Daniel (author), Kooij, Robert (author)Water distribution networks (WDNs) are critical to provide safe, clean drinking water around the globe. However, they are susceptible to accidental or deliberate contamination, potentially resulting in poisoned water, many fatalities and large economic consequences. In order to protect against such intrusions, an efficient sensor network...journal article 2019

Baar, A.W. (author), de Smit, Jaco (author), Uijttewaal, W.S.J. (author), Kleinhans, Maarten G. (author)Large-scale morphology, in particular meander bend depth, bar dimensions, and bifurcation dynamics, are greatly affected by the deflection of sediment transport on transverse bed slopes due to gravity and by secondary flows. Overestimating the transverse bed slope effect in morphodynamic models leads to flattening of the morphology, while...journal article 2018

Uyttenhove, W. (author)This thesis provides a methodology and set-up of a reactivity monitoring tool for Accelerator-Driven Systems (ADS). The reactivity monitoring tool should guarantee the operation of an ADS at a safe margin from criticality.

Vegt, I. (author), Weerheijm, J. (author)Dynamic tests demonstrate an extensive rate effect on the tensile strength as well as the post-peak behaviour beyond loading rates of about 50 GPa/s. One of the possible explanations for the observed rate effects on the fracture behaviour is enhanced resistance by moisture in the pores. To study the influence of the moisture content and pore...conference paper 2016
