The authors proposed estimation formula of allowable shear strength of R/C beams in consideration of residual shear crack width. However, this formula is not applied to R/C columns. The authors conduct tests of R/C columns using 685N/mm2 shear reinforcement under comparative low axial force. Based on these tests result, the precision of estimated allowable and ultimate shear strength of R/C columns is clarified.
