Abstract

Most recent studies on fibre-reinforced self-compacting concrete agree on the impact of the casting conditions on the fibre orientation and distribution, and its consequence thereof on the structural performance. A substantial number of investigations are continuously contributing to gain experience on the use of flowable FRC for different structural applications, and will ultimately serve to define the principles to incorporate the effects of fibre orientation and distribution on design recommendations.
The present paper describes a recent modelling approach that can take into account the configuration of the fibres in a structural element, i.e. their orientation and distribution, to predict the structural performance. The modelling approach has previously been presented and validated for structural elements in which the actual fibre configuration was characterized using Computer Tomography scanning. In this paper, the modelling approach is applied to analyse a wall element whose fibre configuration was obtained using the simulation of the concrete flow during casting.
The integrated simulation of casting and structural performance provides an actual framework to incorporate the effect of the fibre configuration in the prediction of structural behaviour. This should contribute to more reliable and effective use of fibre-reinforced self-compacting concrete.
