The potential of using steel fibres in load-bearing structures is still relatively unknown – in particular in connection with the application of self-compacting concrete, resulting in Steel Fibre Reinforced Self Compacting Concrete (SFRSCC). The structural performance of SFRC is strongly dependent on the fibre orientation and distribution and this holds true in particular for SFRSCC where the flow of the fresh material can cause extreme fibre orientation, which can be viewed as both a weakness and strength of the material.

Development of numerical tools to predict the flow of SFRSCC is important in order to understand the nature of fibre orientation and to benefit from fibre orientation in structural design. This paper presents a study on fibre orientation of SFRSCC in reinforced walls. A relatively large wall trial casting was carried out prior to the construction of an underpass bridge for a new city bypass. A small part of this wall was simulated using a newly developed numerical tool to simulate the flow of SFRSCC. Simulated and measured fibre orientation in three directions have been compared in terms of fibre counts.
