Stroeven, P. (author), He, H. (author)Loose random and dense random mono-size pacl<ing states were investigated by the discrete element modelling (DEM) for eight types of polyhedral grains, for ellipses with different aspect ratio, for cubes and for spheres. Focus was on density, sphericity of the grains and average value and frequency distribution of coordination number. The 3D...conference paper 2013

Kappen, J.M.J. (author), Giardina, G. (author), Hendriks, M.A.N. (author), Rots, J.G. (author)The development of infrastructure in major cities often involves tunnelling, which can cause damage to existing structures. Therefore, these projects require a careful prediction of the risk of settlement induced damage. The simplified approach of current methods cannot account for three-dimensional structural aspects of buildings, which can...conference paper 2013

Amir, S. (author), Van der Veen, C. (author), Walraven, J.C. (author)In the Netherlands, there is a need to determine the capacity of bridge decks as a large number of them were built back in the 60’s and 70’s. Since then, not only a lot of additional safety requirements have been incorporated into the modern codes but the traffic flow has also increased drastically. The current research deals with this question...conference paper 2012

Vandoren, B. (author), De Proft, K. (author), Simone, A. (author), Sluys, L.J. (author)A mesoscopic masonry model is presented using the partition of unity finite element method. Joints are only explicitly introduced when a critical stress state is exceeded, resulting in a computationally more efficient procedure when compared to models in which all joints are a priori active. The performance of the presented model is demonstrated...conference paper 2013

Lantsoght, E.O.L. (author), Van der Veen, C. (author), Walraven, J.C. (author)A large number of existing reinforced concrete slab bridges are found to be insufficient for shear when calculated according to the governing codes. Seeking improved methods, for example, based on new experimental evidence, to assess the residual shear capacity and prolonging their service life can avoid large economic, environmental and social...conference paper 2013

Gresnigt, A.M. (author)The present design rules for fillet welds in Eurocode 3 lead to very thick fillet welds for higher strength steels S420, S460 and S690. Other design rules, e.g. the AISC specification [6] and the Canadian standard CSA-S16-09 [8] give much smaller fillet weld sizes for these steel grades. Another important difference is that the strength of the...conference paper 2014

Weerheijm, J. (author), Vegt, I. (author)Data on the dynamic fracture energy of concrete are scarce and also not consistent due to different test methods, data analyses and definitions. This paper intends to facilitate the discussion on dynamic fracture energy and start the standardization process for dynamic tensile testing. The response and failure mechanisms in statics and dynamics...conference paper 2010

Shionaga, R. (author), Pansuk, W. (author), Grunewald, S. (author), den Uijl, J.A. (author), Walraven, J.C. (author)The synergistic action of a cementitious matrix and fibres can result in strain hardening in tension. The accompanied tensile strain capacity can be an important design parameter for strain-hardening cementitious composites in order to prevent the localization in a single crack and to assure that the stress is at least the tensile strength o f...conference paper 2014

Malagu, M. (author), Benvenuti, E. (author), Simone, A. (author)In this article we investigate the application of high order approximation techniques to one-dimensional boundary layer problems. In particular, we use second order differential equations and coupled second order differential equations as case studies. The accuracy and convergence rate of numerical solutions obtained with Lagrange, Hermite, B...conference paper 2013

Dijkshoorn, G.W. (author), Terwel, K.C. (author), Guldenmund, F.W. (author)During the last few years, several major accidents during the construction phase have occurred in the Dutch building industry. The collapse of a roof structure of the FC Twente football stadium and the collapse of a concrete floor of the B-tower Rotterdam are some recent examples. Consequently, Dutch contractors do need to establish a reliable...conference paper 2013

Sangadji, S. (author), Schlangen, E. (author)Many researchers proposed self healing mechanism using hollow fibres and or microcapsule containing a modifying agent dispersed in the concrete to prolong its service life and make it more durable. A novel self healing concrete concept is proposed in this paper by using porous network concrete components. They are placed at the surface or...conference paper 2012

Polder, R.B. (author), Nijland, T. (author), De Rooij, M. (author), Larsen, C.K. (author), Pedersen, B. (author)Blast furnace slag cement (BFSC) has been used to build reinforced concrete structures in marine and road environment in The Netherlands for nearly a century. The experience is good and structures with long service lives can be obtained, as has been shown by several field studies. This is caused by a high resistance against chloride penetration...conference paper 2014

The application took place in the highlands in Ecuador in July 2014. The concrete was cast as linings for an irrigation canal that transports water from glaciers in the Andean mountains to...conference paper 2015
