In the present study, new constitutive models for high strength steel fibre reinforced concrete (HSSFRC) have been formulated by means of a regression analysis of many experimental data (from literature) by using SPSS-statistical program. This proposed constitutive models have been employed for formulating the material finite element models to study the behaviour of HSSFRC corbels.The corbel is considered in a plane stress state and eight-node Serendipity element has been employed to represent the concrete, a strain hardening plasticity approach is used to model the compression behaviour, the yield condition is formulated in terms of the first two stress invariants, a tensile strength criterion is used to predict crack initiation. The numerical results of proposed material models and corbels behaviour compared with published experimental results showed good agreement.
