“…Moreover, the influence of steel fibre on the post peak behaviour was apparent in comparison with non-fibrous columns. Similar findings were reported by Hadi [27], Aoude et al [28], Aoude et al [29] and Hosinieh et al [30]. Nevertheless, the analytical axial load-bending moment interaction diagram of the RPC column reinforced with different types of steel fibres has not been investigated as yet.…”

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 reinforced 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

“…The failure mechanism of column CRC-318 2%A-75 was tension rebar rupture after Blast 4 (see Figure 7c). It is also noted that this CRC 319 specimen was able to not only match but better control maximum and residual displacements 320 when compared to column SCC-0%-38, which had seismic detailing; see CRC also allows for improved confinement when compared to conventional concrete [31]. 327…”

“…The ductility of SFRC columns influences by the steel fiber aspect ratio [5]. The normalized capacity of the ultra-high performance fiber reinforced concrete columns reached well above 1 due to the contribution of steel fibers to confinement [6]. The use of two or more types of fibers in a suitable combination may potentially improve the overall properties of concrete and also result in performance concrete [7].…”

An experimental investigation is carried out to find the beneficial effect of adding steel fiber to reinforced concrete square columns. Hooked end steel fiber type is used in this investigation. The aspect ratio is 60 and the percentages of the steel fiber that added to the concrete are 0.5%, 1.0% and 1.5%. The experimental work consists of fabricated twenty columns to observe the effect of steel fibers on the axial and bending moment capacity. The specimens are classified into five groups according to the applied load on it. Each of these groups is consisted of four columns having different steel fiber ratios (0, 0.5, 1.0 and 1.5) %. The columns are tested under concentric, eccentric with variable eccentricities and two-point loading. All tested columns in a one group having the same dimensions, same interior reinforcement and were tested under one applying–load and they have a square cross-section with a dimension of (100 × 100) mm. Specimens with steel fiber results are compared with the control specimen of their own (columns mad of plain concrete). The results showed that increasing steel fiber ratio is caused an increasing in the first cracking load and an increase in the ultimate load for all tested columns.
