Finite Element Analysis of Ultra High Performance Fibre Reinforced Concrete Beams Using Microplane Modelling
Ultra high performance fibre reinforced concrete (UHPFRC) exhibits enhanced strength, ductility and durability properties in comparison to conventional and high performance concretes. This research uses results from experimental tests on small scale UHPFRC beams to validate three-dimensional finite element modelling methods developed for concrete beams using microplane theory. The effect of 0%, 1% and 2% fibre volumes were investigated on beams with varying cross-section. Beams with and without conventional steel reinforcement were tested in four point bending. The numerical models accurately replicated the behaviour of the experimental specimens. The load-deflection and failure modes in the numerical beam models provided an accurate representation of the experimental behaviour, including the observed change in failure mode from shear in the ultra high performance concrete (UHPC) beams with conventional steel reinforcement to a flexural failure in their UHPFRC counterparts.
