This paper discusses the hysteresis curve and the limit rotation angle of SRC columns composed of unembedded type column bases under axial tensile force. In the beginning, we describe the mechanical model to carrying out the elasto-plastic analysis. It had been reported in the previous paper that the mechanical model is accurate, but we tried to improve the accuracy of the mechanical model further. Then, in order to discuss the hysteresis curve and the limit rotation angle of column bases, we carried out the numerical analysis by the mechanical model. From the analytical results, an effective way to increase the deformation capacity of column bases were became clear, and we presented the appropriate design method about each column of the first floor in SRC structures.
