The invention provides an industrialized building partition wall beneficial for structural seismic resistance. The industrialized building partition wall is formed by splicing a plurality of prefabricated wallboards, wherein one side of one prefabricated wallboard is provided with an inner layer arc protrusion, the inner layer arc protrusion can be spliced with a groove in another prefabricated wallboard, and after being spliced, the two prefabricated wallboards can be fixed through bolted connection. The building partition wall has the advantages that the prefabricated wallboards are not large in size and easy to splice, facilitate construction and do not affect main body structural seismic resistance, and seismic resistance of a main body structure can be enhanced. Industrial application can be implemented in seismic resistance of buildings.
