Abstract

This study examined the effect of different crack-control approaches at the opening corners on the in-plane shear response of reinforced concrete walls. The conventional diagonal bar arrangement, stress dispersion shell plate, and crack-control strip were considered at each opening corner to mitigate the localized diagonal tension cracks at the re-entrants. Four wall specimens were tested under cyclic in-plane lateral loads. Test results showed that the failure modes and lateral load-displacement relationship of wall specimens were marginally affected by the crack-control approaches considered at the opening corners. Meanwhile, the crack-control strip was more promising than the other approaches in restricting the propagation of diagonal shear cracks at opening corners. The in-plane shear strength of walls with an opening could be reasonably predicted by the ACI 3I8-I9 equation.
