Recently, core wall structures are increasing because of the needs for omitting columns and beams inside living space. It is realized with a new kind structure with ECC coupling beam that consume seismic energy. ECC have larger tensile capacities and crack width restriction effect resulting from small cracks dispersion under tensile stress. However, bond splitting failure of ECC coupling beams has not been grasped well. Therefore, investigations in terms of stress conditions and resisting mechanisms for bond splitting failure have been conducted to suggest new evaluation method. This study is summarized as follows; 1) reinforcing effect due to the tensile capacity of ECC is similar to that of reinforcement. 2) The bond splitting strength of ECC beams without lateral bar is about 1.5 times higher than that of NC beams. 3) New evaluation method was suggested in this study.
