“…The researchers and specifications for the behavior of RC shear walls subjected to pure torsion show a rather poor level of knowledge related to the torsional behavior. Many researchers [15][16][17][18][19][20][21][22][23][24][25] have conducted to study on the effect of seismic performance of the RC shear walls. Nevertheless, many researchers do not have focused on the torsional behavior of the RC shear walls.…”

The shear wall system is one of the most commonly used lateral load‐resisting systems in reinforced concrete (RC) high‐rise buildings. The present work is designed to investigate the behavior of reinforced shear walls upon their hybrid fiber ratio, the horizontal reinforcement ratio, and for the reinforcement aspect ratio. For this purpose, nine‐shear walls were manufactured. The same longitudinal reinforcement ratio and the steel and carbon fibers were the main design concept. Withal, the self‐compacting concrete with fiber hybridization was the general perspective for the RC. All the shear wall models were inspected not only for torsion, but also for the energy dissipation capacity, crack propagation, etc. Torsional moment capacity increased, when the hybrid fiber ratio rose up from 0% to 1.0% and then 1.5%. However, this increase was larger in case of increasing the hybrid fiber ratio from 0% to 1.0%. Increasing the hybrid fiber ratio from 1.0% to 1.5% did not result in a performance increase as in the first case. Increasing the fiber ratio from 0% to 1% and from 1% to 1.5% increased the maximum torsional moment between 7.39% and 33.41%. Torsional moment and twist angle capacities increase with the increase in hybrid fiber and horizontal reinforcement ratio and the decrease in the aspect ratio in RC shear walls. Withal, the energy absorption capacity, ductility, and stiffness are also increased as the hybrid fiber ratio. Increasing the hybrid fiber ratio decreased the crack density in the plastic hinge region. Decreasing the aspect ratio from 1.5 to 1.25 increased the dissipation energy capacity between 68.75% and 100%. The addition of 1.0% fiber, a significant increase in the value of ~30% and 53% was achieved stiffness after the crack.

The purpose of this experimental investigation was to confirm whether the Basalt-Fibre-Reinforced Cement Matrix (BFRCM) effectively enhances the cyclic performance of columns made of reinforced concrete (RC). The BFRCM system, which comprises basalt fabric mesh reinforced with a cementitious matrix containing polyvinyl alcohol (PVA) fibre, has significant practical implications. In the testing phase, concrete and steel reinforcement were used to create RC column specimens, which were then strengthened with three, four, and five layers of BFRCM. The horizontal cyclic and constant axial loads were applied and tested to evaluate the performance of RC columns with and without strengthening. By improving the energy dissipation by approximately 9 to 32% and increasing stiffness by roughly 24 to 44%, the column specimen with three, four, and five layers of BFRCM performed better than the control specimen. Furthermore, incorporating short fibre into the matrix effectively improved the tensile properties of the FRCM systems and decreased the shrinkage-induced cracks. The increased stiffness indicates that the column with BFRCM has better structural strength because it can sustain higher loads with less deflection. The thorough comparative analyses examined the RC column specimens’ failure modes, hysteretic responses, stiffness degradation, and energy dissipation, providing a reliable basis for the conclusions. The test results confirmed that the BFRCM effectively enhanced the seismic capabilities and has been promised a way to strengthen RC elements, providing valuable insights for civil engineering and materials science.
