Wintermans, Marten (author)To align with the objective of the European Green Deal [46] policy of achieving net-zero greenhouse gas emissions by 2050, the construction sector must transition to a circular built environment. Most of the waste in the Netherlands is related to construction and demolition waste, with the industry accounting for approximately 35% of CO<sub>2<...master thesis 2024

Dubbeldam, Nick (author)This research aims to improve the structural safety of wide floor slabs with openings due to embedded non-structural elements. The multidisciplinary design of these slabs has resulted in various safety issues, including errors in the design due to the absence of a calculation method and insufficient integration between designs of different...master thesis 2023

de Sousa, Alex Micael Dantas (author), Lantsoght, E.O.L. (author), Debs, Mounir Khalil El (author)Reinforced concrete one-way slabs under concentrated loads can develop different shear failure mechanisms: as wide beams in one-way shear, punching shear around the load or a mixed mode between them. Until now, most publications presented recommendations to assess the shear capacity considering only the one-way shear failure mechanism. This...journal article 2023

Dantas de Sousaa, Alex Micael (author), Lantsoght, E.O.L. (author), de Lima Araújo, Daniel (author), Pereira Pradoe, Lisiane (author), Debs, Mounir Khalil El (author)This study describes a set of recommendations to improve the precision of shear and punching shear capacity predictions for one-way slabs under concentrated loads, regardless of the governing failure mechanism, using the ABNT NBR 6118:2014 code provisions. For this purpose, a database of 143 test results was developed, including one-way slabs...journal article 2023

Bierkens, G.N.J.C. (author), Grazzi, S. (author), van der Meulen, F.H. (author), Schauer, M.R. (author)We construct a new class of efficient Monte Carlo methods based on continuous-time piecewise deterministic Markov processes (PDMPs) suitable for inference in high dimensional sparse models, i.e. models for which there is prior knowledge that many coordinates are likely to be exactly 0. This is achieved with the fairly simple idea of endowing...journal article 2023

de Sousa, Alex M.D. (author), Lantsoght, E.O.L. (author), El Debs, Mounir K. (author)One-way slabs under concentrated loads may fail by one-way shear such as wide beams, punching shear, flexure, or by combining two or more of these mechanisms. Nevertheless, most publications have only addressed shear and punching failures without flexural reinforcement yielding. This study investigates the ultimate shear capacity of one-way...journal article 2023

Amir, Sana (author), van der Veen, C. (author), Walraven, J.C. (author), de Boer, Ane (author)A large number of bridges in the Netherlands have transversely post tensioned deck slabs cast in-situ between flanges of precast girders and were found to be critical in shear when evaluated by Eurocode 2. To investigate the bearing (punching shear) capacity of such bridges, a 1:2 scale bridge model was constructed in the laboratory and...conference paper 2023

(author), Pérez-Galacho, Diego (author)On-chip spatial and polarization multiplexing has emerged as a powerful strategy to boost the data transmission capacity of integrated optical transceivers. State-of-the-art multiplexers require accurate control of the relative phase or the spatial distribution among different guided optical modes, seriously compromising the optical...journal article 2023

Kraaijenbrink, Lennart (author)With the rise of hydrogen as a green alternative for fossil fuels, the demand for storage capacity of hydrogen increases significantly. Due to the high risk of explosions in urban environments it brings along, the blast analysis of buildings within in range of the explosions becomes more relevant.<br/><br/>The goal of this research is to develop...master thesis 2022

Carrera, Bernardo (author), Lantsoght, E.O.L. (author), Alexander, Scott D.B. (author)The strip model describes a load path prior to failure that can be tailored to a wide range of slabs under concentrated loads, both concentric and eccentric. Eccentric punching shear can occur in concrete slab-column connections subjected to shear and unbalanced moment, such as edge and corner columns. This paper shows how the strip model is...conference paper 2022

Chumyen, P. (author), Connolly, D.P. (author), Woodward, P.K. (author), Markine, V.L. (author)Railway track transition zones are areas where there is a sudden change in the track-ground structure. They include changes between ballasted and slab track, bridge approaches, and tunnel entry/exits. They are often the location of rapid track deterioration, and therefore this paper investigates the use of auxiliary rails and soil improvement...journal article 2022
