Concrete shear walls are reinforced with both horizontal and vertical reinforcement (Figure&nbsp;4). A reinforcement ratio is defined as the ratio of the gross concrete area for a section taken orthogonal to the reinforcement. Construction codes of practice define maximum and minimum amounts of reinforcement as well as the detailing of steel bars. Common construction methods for in-situ reinforced concrete walls include traditional shuttered lifts, slip form, jump form and tunnel form.
