Parametric analysis of slotted concrete shear walls reinforced with shape memory alloy bars

Reinforced concrete (RC) walls are the primary lateral resistance components selected for buildings located in active seismic areas. Special designs and details are typically applied to dissipate energy through inelastic deformation; such a design approach results in significant permanent damage. Th...
