An optimisation approach for mechanical and durability properties of hybrid fibre-reinforced concrete using steel and sisal fibres

This article proposes an optimisation approach for improving the performance of hybrid fibre-reinforced concrete (HFRC) in compression with varying fibre content. The proposed approach uses the Atomic Orbital Search (AOS) control scheme. The major objective of the proposed method is to raise the compressive strength, tensile strength and flexural strength of sisal fibre. The AOS approach is used to predict the stress-strain issues and provides an optimal solution. The Hybrid fibres combine multiple fibre types, which significantly improves ductility and energy absorption while the capability is compared to single-type fibre additions. By then, the proposed model is implemented in MATLAB/Simulink working stage and the execution is calculated with the proposed method. The compressive strength in HFRC is 47.6, split tensile strength in HFRC is 6.12, flexural strength in HFRC is 8.81, water absorption in HFRC is 0.67 and the mass loss in HFRC is 97.3. From the result, it concludes that the performance of hybrid fibre-reinforced concrete is improved.
