Two half-scale R/C column specimens were constructed and tested under varying axial loads to investigate the shear behavior and the ultimate shear strength. One specimen (C specimen) was modeled the soft-first story column of the condominium which was heavily damaged in the 2016 Kumamoto Earthquake. Another specimen (CW specimen) had a thick wing wall with sufficient confinement on either one side. Both specimens failed in shear, and the maximum capacity of CW specimen was approximately 1.9 times that of C specimen. Three-dimensional FE analysis was conducted and captured the experimental maximum capacity of both specimens in good accuracy. Based on the results of a parametric study using FE analysis, some modifications were added to the existing numerical evaluation and improved its prediction accuracy.
