The result ofinvestigation show that setting vertical slits in the shear wall can turn the failure pattern of the shear wall from shear-mode into bend-mode. If vertical slits were set properly, the transformative property of the shear wall was improved greatly and the seismic behavior was excellent under the condition that the bearing capacity decreased slightly.
