Leonetti, D. (author), Maljaars, J. (author), Snijder, H.H. (author)Before bolts were invented, hot-riveting was employed as technological process to produce built-up structural members of steel structures. Nowadays, these structures being still in service and susceptible to fatigue failure,they need to be assessed for their remaining service life. To estimate the fatigue life distribution of riveted connections...article 2019

Het is nog maar een idee, maar als het door de kassenbouw-wereld wordt opgepakt kan het een grote verandering inlui-den. Piet Bom, oprichter van Bom Kassenbouw, heeft een alter-natief bedacht voor aluminium in het kasdek: fiberglass, ofwel kunststof versterkt met glasvezel. De innovatie is genomineerd voor de GreenTech Concept Awardarticle 2019

Het 'Kozijn van de Toekomst' TNO en FSC Nederland werken aan een project om houten kozijnen nog duurzamer toe te passen in de woningbouw. Hierbij wordt een aantal ketenpartners vanuit houtindustrie, bouw en opdrachtgevers actief betrokken. De belangstelling voor de werksessies is groot. Op 3 december worden de resultaten gepresenteerdarticle 2019

Jacobs, P. (author)TNO en Hamwells willen het tapwatergebruik voor douchen fors verminderen met een douchekraan met ingebouwde warmteterugwinning. Bij de één gemonteerd achter een elegant paneel, bij de ander in een geïsoleerde douchecabine. Een boiler van vijftig en tien liter volstaat voor een comfortabele douche.article 2019

Maljaars, J. (author), Leonetti, D. (author), Maas, C. (author)Many existing steel bridges are constructed by using hot-driven steel rivets as fasteners. It is known that the fatigue strength of these joints depends on their geometry, since it affects the load transfer mechanism and, therefore, the severity of the stress concentration. Attempts have been taken in the past to provide the characteristic...article 2019

Ritzen, M.J. (author), Houben, J.J.M. (author), Rovers, R. (author), Vroon, Z.A.E.P. (author), Geurts, C.P.W. (author)To fulfil (part of) the electricity demand of buildings, photovoltaics (PV) can be added to the building envelope (BAPV) or integrated in the building envelope (BIPV). To assess environmental impact, Life Cycle Assessment (LCA) tools are applied. In this study, an LCA method is developed for BIPV configurations. The LCA is applied on three...article 2018

Nedeljkovic, M. (author), Šavija, B. (author), Zuo, Y. (author), Lukovic, M. (author), Ye, G. (author)The aim of this paper was to investigate the effect of natural carbonation on the pore structure, and elastic modulus (E-m) of alkali-activated fly ash (FA) and ground granulated blast furnace slag (GBFS) pastes after one year of exposure in the natural laboratory conditions. The chemical changes due to carbonation were examined by X-ray...article 2018

Visser, J.H.M.

Maljaars, J. (author), Bonet, E. (author), Pijpers, P.J.M. (author)Steel orthotropic decks in bridges and ferries have shown to be prone to fatigue cracking. A typical fatigue crack observed in these structures initiates at the root of the weld between the deck plate and stringer and grows into the deck plate. Due to limited fatigue test data available and the deviating characteristics of this type of crack as...article 2018

TNO heeft een vereenvoudigde, indicatieve methode bedacht voor het bepalen van de luchtdichtheid van gebouwen. Bij grote woningbouwprojecten worden vaak maar enkele huizen op luchtdichtheid getest, vanwege het tijdsbestek en de kosten. Met deze methode wordt het mogelijk alle afgewerkte woningen te testen. De methode is bovenal indicatief en is...article 2018

Gómez, S.S. (author), Geurts, C.P.W. (author), Metrikine, A. (author)In this paper, the overall damping as function of the velocity of vibration of two tall structures subjected to wind is studied. The overall damping ratio is studied by means of two simple, but representative and complementary models and it is compared with that identified in two buildings in The Netherlands. In the models, the soil-structure...article 2018

Lubelli, B.A. (author), Nijland, T.G. (author), Tolboom, H.J. (author)Tuffstone elements with a large length/width ratio often suffer damage in the form of cracks parallel to the surface and spalling of the outer layer. This study aimed at verifying if this damage may be the result of a differential dilation between parts with different moisture content. The research, carried out on Ettringen and Weibern tuff,...article 2018

van Es, S. (author), Slot, H. (author), Steenbergen, H. (author), Maljaars, J. (author), Pijpers, R. (author)In Memoriam of Prof. Dr. Bernt Johansson. The use of high-strength steels (HSS, 460 < fy ≤ 700 MPa) and particularly very high-strength steels (VHSS, fy > 700 MPa) is limited in steel structures in civil and offshore engineering. This is due to a lack of experience in structures made of these materials and a lack of understanding of the...article 2018
