Abstract


  • This paper presents analytical modelling of the axial-flexural behaviour of Reactive Powder Concrete (RPC)

    columns reinforced with and without steel fibres of different types (industrial and waste) in individual and

    hybrid forms. An analytical stress-strain model for unconfined RPC was used for the analysis of the axial loads

    and bending moments of the fibrous RPC columns. The layer-by-layer numerical integration method was used to

    calculate the axial load and bending moments in this study. The analytically developed axial load-bending

    moment (

    P-M

    ) interaction diagrams were validated by using experimental results from the literature. A para-

    metric study was carried out to investigate the influence of the properties of steel fibres on the axial-flexural

    behaviour of fibrous RPC columns. It was found that the analytical unconfined stress-strain model used in this

    study well estimates the maximum axial loads and the maximum bending moments of the RPC columns re-

    inforced with and without different types of steel fibres. Also, the influence of the properties of steel fibres is

    more pronounced at eccentric and flexural loading
