The invention relates to a hybrid energy-dissipating plastic hinge with non-linear rigidity. The hybrid energy-dissipating plastic hinge comprises a first rotating unit and a second rotating unit which are rotationally connected through a rotary shaft. The hybrid energy-dissipating plastic hinge further comprises a viscous energy-dissipating unit and a spring energy-dissipating assembly. The viscous energy-dissipating unit comprises a cylindrical box, a limiting assembly arranged on the outer wall of the cylindrical box, and a viscous liquid partition assembly. The exterior of the cylindricalbox is fixedly connected with the second rotating unit, and the cylindrical box is internally loaded with viscous liquid. The cylindrical box and the rotary shaft are coaxially arranged. During normaluse and small earthquakes, a limiting unit provides rotating rigidity, and the plastic hinge is a rigid joint; and during medium earthquakes and large earthquakes, a limiting pin is sheared, the plastic hinge relatively rotat
