The invention discloses a multi-storey and high-rise assembly type modularized self-resetting steel-structure special-shaped column frame system, and belongs to the technical field of structural engineering. The frame system comprises outer joint modules, corner joint modules and inner joint modules. The invention provides a novel assembly type module. Joints and inflection points of an intercepted frame part are assembled as a whole, the inflection points of the frame part are small in bending moment, a weak connection mode can be adopted between columns, a connection mode is flexible, and steel consumption and connection difficulty are reduced. Due to the design of prestress steel strands, the post-earthquake residual deformation of frame joints can be reduced, and the self-resetting effect is achieved. Due to the arrangement of supporting plates, cover plates and outer ribs, beams can be precisely positioned, and meanwhile the stability of the joints is improved. The outer ribs are arranged in beam flanges, so local bearing capacity is improved, and meanwhile the attractiveness effect can be achieved. In production and construction of the steel-structure system, modularization, factorization, standardization and assemblage are combined, industrialized production is achieved, and construction cost is reduced.
