This material has good workability in the fresh state and exhibits strain-hardening and multiple cracking characteristics of high-performance fibre-reinforced cementitious composites (HPFRCC) in the hardened state. The use of steel fibers in a reinforced concrete column can replace the number of transverse reinforcement without reducing column strength and deformation capacity. Several experimental studies on the cyclic behavior of HF-SHFRC columns were carried out to capture the big picture of the feasibility study of steel fibers to substitute the transverse reinforcement. However, information regarding the numerical model of steel fibers reinforced concrete column, particularly column subjected to displacement reversals, is very limited. In this paper, an analytical macro model for HF-SHFRC columns subjected to lateral displacement reversals and high axial loading level is developed. The steel fibers are converted into transverse reinforcement in order to obtain equivalent confinement. In general, the cyclic behavior of the HF-SHFRC column could be predicted. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.Buckling spring; Equivalent bond strength; Equivalent confinement; Fiber effectiveness factor; Highly-flowable strain hardening fiber reinforced concrete (HF-SHFRC); Shear spring; Toughness ratio[SDGs]SDG11Axial loads; Bond strength (materials); Concrete construction; Numerical models; Reinforced concrete; Reinforced plastics; Shear flow; Steel fibers; Buckling spring; Effectiveness factor; Equivalent bond strength; Equivalent bonds; Equivalent confinement; Fiber effectiveness factor; Fiber-reinforced concretes; Highly-flowable strain hardening fiber reinforced concrete; Shear spring; Toughness ratio; Strain hardeningconference paper10.1007/978-981-16-7924-7_172-s2.0-85128754440
