Behavior of low-rise shear walls was investigated under simulated seismic loading. Large scale wall specimens were tested under inelastic load reversals. Shear sliding was observed in specimens with low aspect ratio. Sliding took place along the critical section at construction joint, when diagonal tension failure was prevented by adequate reinforcement. Shear sliding resulted in premature wall failure and reduced deformability of the member. A special type of reinforcement was developed to prevent shear sliding. This reinforcement consisted of short bars, crossing the critical section, placed in between the longitudinal reinforcement. It controlled the critical flexural crack along the construction joint, and produced concrete shear keys by affecting the crack pattern in the critical region. Shear sliding was completely eliminated in specimens with sliding shear reinforcement.
