Seismic performance of a novel interior precast concrete beam-column joint using ultra-high performance concrete

•Four interior UHPC/RC composite beam-column joints are cyclically tested.•Parameters including stirrup ratios, anchorage methods and lengths are studied.•The UHPC can be safely used in the joint zone without any stirrups.•The anchorage length of the beam longitudinal bars can be reduced in the UHPC joint zone.
