Using of new technique to reinforce concrete structures is needed to improve their
strength against unexpected loads such as earthquake. The Computer Numerical
Control (CNC) technique is one of the modern ways to configure the steel plate in
any desired shape. RC shear wall is one of the important structural elements in the
buildings. Reinforcing of concrete shear wall by embedded CNC steel plate instead
of steel bars has been proposed in this study under cyclic loading. To implement
the investigation of the new technique of reinforcement, a numerical simulation of
the concrete shear wall specimen reinforced with ordinary steel bars under cyclic
loading combined with vertical uniaxial load has been adopted from previous
literatures. The numerical results have been verified with a selected experimental
case results in term of hysteresis behaviour of the RC wall model. Then, the
comparison in seismic behaviour of the ordinary and the proposed reinforcement
technique of concrete shear wall model has been exhibited. Furthermore, three
varied parameters have been inspected to explain the efficiency of the new
technique. The parametric study includes reducing the thickness of steel CNC plate,
cyclic loading path and steel yield strength. The results show significant
enhancement of concrete wall strength by increasing the ultimate loading capacity
when using embedded steel CNC plate technique by 173% with appropriate energy
dissipation capacity. The new technique could be alternative process than
traditional ways in the precast building construction industries to correspond the
modern method of robot-based construction, as well to reduce the cost
