Xin, L. (author), Markine, V.L. (author), Shevtsov, I. (author)The procedure for analysing rolling contact fatigue crack initiation and fatigue life prediction of the railway turnout crossing is developed. A three-dimensional finite element (FE) model is used to obtain stress and strain results, considering the dynamic effects of wheel-crossing rolling contact. Material model accounting for elastic- plastic...conference paper 2015

Ma, Y. (author), Markine, V.L. (author)In the present paper, a numerical procedure for surface crack initiation analysis based on the critical plane approach is proposed. The complex stress/strain state of wheel and rail (W/R) contact is analysed by means of submodelling approach together with the transient contact nodal loads obtained from dynamic W/R rolling contact analysis....conference paper 2015

Idarraga Alarcon, G.A. (author), Burgelman, N.D.M. (author), Meza Meza, J. (author), Toro, A. (author), Li, Z. (author)This work investigates the energy dissipation in a wheel/rail system through friction work modeling. In order to identify the effect of the friction coefficient on the energy dissipation in the wheel/rail contact, several simulations were performed using a 3D multibody model of a railway vehicle implemented in the software package VI-Rail Adams,...conference paper 2015

Van de Straat, R. (author), Hofman, S. (author), Coenders, J.L. (author), Paul, J.C. (author)The new Transfer Hall in Arnhem is one of the key projects to prepare the Dutch railways for the increased future demands for capacity. UNStudio developed a master plan in 1996 for the station area of which the completion of the Transfer Hall in 2015 will be a final milestone. The Transfer Hall is a merging point of passengers, commercial and...conference paper 2015

Van Eck, S. (author), Coenders, J.L. (author), Doomen, R. (author)A solar updraft tower is a type of power plant which uses solar irradiation to generate electricity. It consists of three elements: a solar air collector, wind turbines and a chimney. The proposed concepts for this chimney schematise it as a 1-km-tall reinforced concrete shell, which are vulnerable to resonance induced by storm actions. This...conference paper 2015

Woodington, W. (author), Bergsma, O.K. (author), Schipper, H.R. (author)A composite textile reinforced concrete (TRC) material is developed to overcome the difficulties of constructing double-curved freeform structures. This is possible by shear-deformation of the woven reinforcement. It affects the direction of reinforcement and thickness, resulting in variable orthotropic properties over the surface. The research...conference paper 2015

Bovenberg, A. (author), Rolvink, A. (author), Coenders, J.L. (author)The adoption of computation in the building industry has led to the development of a range of tools intended for design. Although commonly used for detailed analysis (FEA) and documentation (CAD/BIM), few tools address the needs of the early design stages for flexibility and quick, insightful feedback and documenting the justification of design...conference paper 2015

Wang, H. (author), Markine, V.L. (author), Dollevoet, R.P.B.J. (author), Shevtsov, I.Y. (author)Transition zones in railway tracks are locations with considerable changes in the vertical stiffness of the rail support. Typically they are located near engineering structures, such as bridges, culverts, tunnels and level crossings. In such locations, the differential settlement always exists and continually grows without proper maintenance....conference paper 2015

The strategy goal is overcoming the reuse design strain through implementation of a genetic algorithm. This algorithm is calibrated to search for a structural frame configuration, while using a reusable element set, meeting floor...conference paper 2015

(author)The production of architectural elements with complex geometry is challenging for concrete manufacturers. Computer-numerically-controlled (CNC) milled foam moulds have been applied frequently in the last decades, resulting in good aesthetical performance. However, still the costs are high and a large volume of waste is produced. This paper...conference paper 2015

It attempts to take advantage of the efficiency of macroscopic models and the accuracy of the mesoscopic models. The solving procedure is, through the coupling of individual approaches, beginning from the largest scale to...conference paper 2015

(author)In 2008 Europe introduced the CEN standards for Asphalt Concrete. The Netherlands adopted the approach of functional requirements, rather than empirical, recipe based requirement. The experiences since 2008 showed that, although this approach allows for a better, more fundamental understanding of Asphalt Concrete, the current understanding is...conference paper 2015
