Column-to-nuki connections are important to evaluate the seismic performance of traditional timber shrines and temples. These connections include several joint types, one of which is the oblique scarf joint. However, few previous studies have examined the column-to-nuki connections of the oblique scarf joint and no design equations exist for them. Thus, this study aims to evaluate the structural performance of column-to-nuki connections in traditional timber shrines and temples based on the full-scale tests. It is shown that the theoretical value of 50 % continuous nuki can safely evaluate the experimental value of the oblique scarf joint.
