The invention relates to a displacement amplification type double-rod viscous damping wall. Two ear plates are fixedly installed on two sides at the upper end of a damping wall body. The ear plates are movably connected with vertical transmission steel plates through first hinged shafts, the tops of the transmission steel plates are movably connected with transversely arranged horizontal actuating rods through second hinged shafts, the bottoms of the transmission steel plates are movably connected with transversely arranged piston rods through third hinged shafts, and the piston rods are fixedly connected with steel plates movably installed in the damping wall body. When dangers happen, the transmission steel plate delivers shearing force to the piston rods by aid of the horizontal movement actions of the horizontal actuating rods, and the piston rods drive the inner steel plates to move laterally in energy consumption liquid to effectively generate shearing blockage force and dissipate energy. The displacement amplification type double-rod viscous damping wall is reasonable and stable in product design and efficient and quick in operation; the piston rods have large displacement, the horizontal displacement of the piston rods is amplified through the unique design of the hinged shafts, corresponding horizontal displacement speed is amplified, and the energy-dissipating capacity of the damping wall is greatly improved.
