Based on the test results of walls with Grade 550 MPa and aspect ratio of 2.0, it was found that the behavior of the wall is close to that of wall with Grade 420 MPa, which is the maximum permissible strength of shear reinforcing bars in ACI 318 (or ACI 349). The findings can be used as an evidence to increase the permissible maximum strength of shear reinforcing bars for shear walls with aspect ratio less than 2.0 in ACI 318(or ACI 349).
