Liu, D. (author), van den Boom, S.J. (author), Simone, A. (author), Aragon, A.M. (author)We propose an enriched finite element formulation to address the computational modeling of contact problems and the cou pling of non-conforming discretizations in the small deformation setting. The displacement field is augmented by enriched terms that are associated with generalized degrees of freedom collocated along non-conforming interfaces...article 2022

Koppen, S. (author), van der Kolk, M. (author), van den Boom, S.J. (author)Real-world structural optimisation problems involve multiple loading conditions and design constraints, with responses typi cally depending on states of discretised governing equations. Generally, one uses gradient-based nested analysis and design approaches to solve these problems. Herein, solving both physical and adjoint problems dominates...article 2022

Egter van Wissekerke, N.G. (author)De NZa ziet nachtsluiting van seh’s waar ’s nachts weinig patiënten komen als een oplossing voor de arbeidsmarktproblematiek. Dit wordt echter niet met data onderbouwd. Daarom heeft TNO in opdracht van de Vereniging Samenwerkende Algemene Ziekenhuizen (SAZ) met data inzichtelijk gemaakt hoeveel personeelswinst er is bij een eventuele sluiting...article 2022

van Heumen, S.P.M. (author)Goede richtlijnen voor het binnenklimaat in de langdurige zorg zijn er nog niet. Vandaar dat TNO onderzoekt van welke richtlijnen zorginstellingen moeten uitgaan om cliënten en medewerkers een optimaal binnenklimaat te bieden. Op basis van dit onderzoek stelt Stichting Binnenklimaattechniek een Programma van Eisen op voor de langdurige zorg.article 2022

Maljaars, J. (author), Leonetti, D. (author), Hashemi, B. (author), Snijder, H.H.B. (author)This paper presents a probabilistic framework to derive the safety factors for fatigue of steel and composite steel concrete road bridges. Engineering models are used for the design and the safety factor is derived in such a way that the design meets the target reliability set by international Eurocode and ISO standards, estimated using measured...article 2022

Snijder, H.H. (author), Knipping, J.B.N. (author), Maljaars, J. (author), Teeuwen, P.A. (author)Capacity design for bolted connections in tension means that yielding of the gross cross-section is decisive over the ultimate resistance of the net cross-section. If the requirement for capacity design is met, ductile connection behavior is achieved, and brittle failure is avoided. However, in many practical cases the bolt holes are too large...article 2022

Allaix, D.L. (author), Bigaj-van Vliet, A.J. (author), Visser, J.H.M. (author), Valcke, S.L.A. (author)The European Green Deal published by the European Commission in December 2019 has set the target of 50% reduction of CO2 emissions and primary material consumption by 2030 compared to the 1990 levels. The construction sector is one of the key sectors where significant improvements are necessary for reaching the European targets. Among the...conference paper 2022

(author), Godoi Bizarro, D.E. (author), Szklarz, S.P. (author), Barros, E. (author)Sustainable development is a complex, multi-disciplinary and multi-sectoral challenge with often contradicting objectives. As such, in the strongly fragmented construction sector often only single aspects of the challenge are subject of innovations. Therefore the construction sector faces a huge challenge to meet multiple goals set a.o. in the...conference paper 2022

Xu, Q. (author), Hofmeyer, H. (author), Maljaars, J. (author), van Herpen, R.A.P. (author)A sandwich panel, as a very important component in building façade systems, consists of two thin walled plates plus an insulation core. For this core, traditionally materials like mineral wool have been used. However, polymer composites are increasingly used instead, for among others their higher stiffness, and better resistance to wind and...conference paper 2022

Nahar, S. (author), Porot, L. (author), Apostolidis, P. (author)In the past years, the use of liquid additives as bitumen modifiers has increased to tailor the rheology of bitumen for a wide range of applications. Their chemical composition and mutual interaction result in specific phase morphologies in the binders. Hence, there is a need to evaluate the phase morphology of complex binders and the impact of...article 2022
