The Behaviour of Hybrid Fiber RC Shear Walls Subjected to Monolithic Pure Torsion: An Analytical Study

The reinforced concrete (RC) shear walls are widely used to serve as the primary lateral loadresisting member in the high-rise buildings. An experimental investigation and analysis of

the mechanical behaviour of hybrid fiber reinforced self-compacting concrete (HFRSCC)

shear walls under pure torsion moment is presented in this paper. The nine HFSCC shear

walls with the same height and longitudinal reinforcement ratio analytically were tested

under pure torsion moment and no axial load. The effect of hybrid fiber ratio and horizontal

reinforcement amount and aspect ratio on the failure characteristics, torsional behaviour,

energy dissipation capacity of squat shear walls was studied. Result indicate that both hybrid

and horizontal reinforcement ratio are increased the maximum torsional moment capacity

and twist angle and that the hybrid fiber ratio is the key parameter that determines the

failure mode of the HFSCC shear walls.
