Awasthy, Nikhil (author), Schlangen, E. (author), Hordijk, Dick (author), Šavija, B. (author), Lukovic, M. (author)Concrete is characterized in terms of its engineering properties, mainly strength and stiffness, which are subsequently used in structural design. However, the apparent (i.e., measured) concrete properties are not intrinsic but dependent on the conditions under which the measurement is performed. Herein a combined experimental and numerical...journal article 2023

Wang, Yi (author), Zhang, Mingzhong (author)Strain hardening geopolymer composites (SHGC) as a tailored group of fibre reinforced geopolymer composites are featured by large tensile strain capacity with multiple micro-cracks. This paper experimentally investigates the strain hardening behaviour of SHGC in terms of flexural stress-deflection response, failure mode and cracking, flexural...conference paper 2021

Abad, Belkis Filian (author), Lantsoght, E.O.L. (author), Yang, Y. (author)The Critical Shear Displacement Theory (CSDT) was developed to determine the shear capacity of reinforced concrete beams based on the different shear-carrying mechanisms (concrete in the compression zone, aggregate interlock, and dowel action). This research aims at extending the CSDT to Steel Fibre Reinforced Concrete (SFRC) by adding the...conference paper 2019

Radtke, F.K.F. (author)Failure patterns and mechanical behaviour of high performance fibre-reinforced cementitious composites depend to a large extent on the distribution of fibres within a specimen. A discrete treatment of fibres enables us to study the influence of various fibre distributions on the mechanical properties of the material. The numerical analysis of...doctoral thesis 2012

Radtke, F.K.F. (author), Simone, A. (author), Sluys, L.J. (author)We present two approaches to model fibre reinforced concrete. In both approaches, discrete fibre distributions and the behaviour of the fibre-matrix interface are explicitly considered. One approach employs the reaction forces from fibre to matrix while the other is based on the partition of unity finite element method. In none of the methods...conference paper 2009

Schumacher, P. (author), Walraven, J.C. (author), Den Uijl, J.A. (author), Bigaj-van Vliet, A. (author)Steel fibres are known to enhance the toughness of concrete in compression and in tension. Steel fibres also improve the bond properties between concrete matrix and reinforcing steel bars. In order to investigate the effect of steel fibres on the rotation capacity of reinforced concrete members, four simply supported beams were loaded in three...journal article 2009

Grünewald, S. (author)The development of self-compacting concrete (SCC) marks an important milestone in improving the product quality and efficiency of the building industry. SCC homogenously spreads due to its own weight, without any additional compaction energy and does not entrap air. SCC improves the efficiency at the construction sites, enhances the working...doctoral thesis 2004
