Lubelli, B.A. (author), des Bouvrie, E. (author), Nijland, T.G. (author), Kamat, A. (author)Salt crystallization is a major cause of weathering of mortars, including plasters and renders. In the last decade, the use of mixed-in salt crystallization inhibitors in mortars has been proposed as a solution to improve the durability of this material with respect to salt decay. Laboratory characterization and accelerated weathering tests have...article 2023

Vibration Measurements on a Cable-Stayed Cyclist Arch Bridge for Assessment of the Dynamic BehaviourVerdenius, S.A. (author), Bronkhorst, A.J. (author), Geurts, C.P.W. (author)The new cable-stayed arch bridge Tegenbosch (Eindhoven, the Netherlands) needed an assessment of its dynamic behaviour under wind loading due to its slender design. Because of wind-induced vibration issues on a number of bridges in the Netherlands with similar designs, it was decided to examine if vortex excitation, wind-rain induced vibration,...conference paper 2023

Bronkhorst, A.J. (author), Moretti, D. (author), Geurts, C.P.W. (author)This paper describes the application of the Frequency Domain Decomposition (FDD) technique on measured acceleration data on the residential tower New Orleans in Rotterdam, the Netherlands. The goal of this study is to determine and analyse multiple natural frequencies and mode shapes of this tower. A measurement campaign was setup on the 158 m...conference paper 2023

Koene, F.G.H.F. (author), Eslami-Mossallam, B.B. (author)Future energy infrastructures are expected to be smart, with the application of energy storage and demand-side management strategies. To size the energy storage and assess the flexibility of the heat demand in a district, insight into its heat demand profile is a prerequisite. A tool was developed to generate the hourly space heating demand of a...article 2023

Viera, J. (author), Aguilar, J. (author), Rodriguez-Moreno, M. (author), Quintero-Gull, C. (author)Analyzing energy consumption is currently of great interest to define efficient energy management strategies. In particular, studying the evolution of the behavior of the consumption pattern can allow energy policies to be defined according to the time of the year. In this sense, this work proposes to study the evolution of energy behavior...article 2023

Verdenius, S.A. (author), Hengeveld, S.T. (author), Maljaars, J. (author)Train axle load measurements performed between 2012 and 2019 at 87 locations in the Dutch railway network are used to evaluate fatigue of railway bridges. The theoretical fatigue damage using realistic influence lines is determined for the measured loads and for the load model from Eurocode EN 1991-2 Annex D. It appears that this load model is ...article 2023

Rodenburg, J.D. (author), Maljaars, J. (author), Hengeveld, S.T. (author), Vervuurt, A.H.J.M. (author)The fatigue life of orthotropic steel bridge decks in road bridges depends on the load effects exerted by heavy lorries. The contact surface of tyres is one of the important variables. Measurements described in the literature demonstrate that the actual tyre contact surfaces of today's traffic representative for Europe are shorter and slightly...article 2023

Sapounas, A. (author), Molhoek, M.S. (author), Bezemer, R.A. (author)De gewasontwikkeling en de oogstplanning in een kas zijn gebaat bij een homogeen kasklimaat. Echter, zelfs bij gebruik van geavanceerde systemen kan het klimaat nog behoorlijk inhomogeen zijn. Een inhomogeen kasklimaat en een daaraan gerelateerd niet uniform groeiend en producerend gewas zorgt voor een hoger energiegebruik. De teler zal te allen...report 2022

(author)Fine recycled concrete aggregates (fRCA, 0–4 mm) are produced from demolished concrete structures and consist of natural aggregates and old cement mortar. The presence of old cement mortar has detrimental effect on the fresh properties and trength of new concrete. This study aims to investigate the working mechanism and effectiveness of...article 2022

Chai, X. (author), Rozsas, A. (author), Slobbe, A. (author), Teixeira, A. (author)This paper investigates the impact of structural health monitoring (SHM) on the failure probability of a simulated sheet pile wall system. We use Bayesian statistics to estimate non-directly observable soil parameters from measured structural responses. These estimates are used to calculate the failure probability of the structure against...article 2022

(author)This paper presents two full-scale fire resistance tests of sandwich panels with connections, to verify one way coupled fire-structure simulations. The heat transfer simulations agree well with the tests, however, the structural response simulations show some differences compared to the start of the first test, which is a sandwich panel façade....conference paper 2022
