Prefabricated structures have the advantages of short construction period, fast construction speed, and low environmental pollution. Based on this, a new type of prefabricated beam column node with energy dissipating steel plates is proposed. The structure mainly consists of prefabricated beams, columns, prefabricated energy dissipating hinge structures, etc. A finite element model is established for analysis and comparison with cast-in-place structures. It is found that the seismic performance of prefabricated beam column nodes with energy dissipating steel plates is better, and their displacement ductility and energy dissipation capacity are much higher than cast-in-place structures. A prefabricated frame structure system with energy dissipating steel plates is established to study its structural failure sequence.
