Reinforced concrete wide beam–column connections have been used in low‐to‐moderate seismicity regions despite little information being available on their seismic performance. This research was conducted to clarify experimentally the hysteretic behaviour and ultimate energy dissipation capacity (UEDC) of this type of existing connection under lateral dynamic earthquake loadings. For this purpose, ⅔ scale models were constructed and tested on a shaking table until they collapsed. The exterior connection behaved as a strong column–weak beam mechanism, and the interior connection as a weak column–strong beam mechanism. The averaged UEDC of the connections in each domain of loading, normalized with respect to the product of the yield strength and yield displacement, were about 6 and 5 for the exterior and interior connections, respectively.
