Seismic design provisions for beam-column joints in the AIJ guidelines are based mainly on earlier experimental studies. However, it is necessary to establish a more rational, performance-based design method, especially for joints subjected to two directional seismic forces. This can be accomplished by analytical study of the stress transfer mechanisms in joints. In order to understand the progression of damage in joint concrete, accumulated absorbed strain energy for concrete and reinforcement was calculated from the results of FEM analysis. The stress transfer mechanisms and progression of damage in concrete and reinforcement provide a basis for establishing a more rational, performance-based design method for RC structures.
