Four full-scale reinforced concrete interior beam-wide column joints were tested under seismic loading. Two as-built Specimens A1 and A2 representing the joint regions in a reinforced concrete wide-column moment resisting frame, which were designed according to BS 8110. The other two modified Specimens M1 and M2 were identical to A1 and A2, but with the alternative reinforcing detailing. The experimental results showed that two as-built specimens failed at a low displacement ductility level, while the other two modified specimens reached a limited displacement ductility level. It was also demonstrated that even limited seismic detailing could improve the seismic behaviour of the joints.
