The invention relates to a prefabricated combined beam and column node member. The prefabricated combined beam and column node member comprises a cross beam and a vertical column which are intersected, wherein the cross beam as well as the vertical column comprises an ECC (engineered cementitious composite) material, longitudinal bars and stirrups, and a rectangular region where the cross beam and the vertical column are intersected and superposed is in the transverse width of A and the longitudinal height of B; the cross beam is in the transverse width of 2B plus A and the longitudinal height of B, and the longitudinal bars penetrate the full length of the cross beam and extend out of two beam ends by 10cm-15cm; and the vertical column in the longitudinal height of 2A plus B, and the longitudinal bars penetrate the full length of the vertical column and extend out of the two column ends by 10cm-15cm. The prefabricated combined beam and column node member disclosed by the invention is the prefabricated member which is formed by casting the steel bar-reinforced ECC material and is applied to an anti-seismic key part, in particular to a key node. Compared with an ordinary reinforced concrete member, the prefabricated combined beam and column node member can significantly improve the ductility and the anti-seismic performance of the structure, greatly reduce the use of the stirrups at the node under the condition of meeting the anti-seismic requirement and solve the difficult problem in construction caused by too dense stirrups in a node region.
