摘要

A numerical model based on the concept of smeared cracking to predict the structural behaviour of reinforced steel-fibre concrete deep beams is developed. Material parameters, which are necessary to formulate a constitutive relation for randomly oriented short steel-fibres under biaxial states of stress are systematically quantified and implemented in the DIANA finite element program. The developed material model is utilised to simulate the structural behaviour of the experimentally investigated reinforced steel fibre concrete deep beams found in the literature. The model is shown to give a very good prediction of the observed ultimate load-carrying capacity and the load-displacement behaviour of the deep beams failed in shear.
