Abstract: The present disclosure discloses a low-frequency vibration-isolating superstructure unit, a superstructure and a method of designing a superstructure, is capable of solving the problem that it is difficult to meet the requirements of miniaturization and lightening of vibration-isolating devices, and the problem of reduced structural rigidity and strength caused by vibration isolation. The low-frequency vibration-isolating superstructure unit includes: an outer protective structure (1), an inner mass block (2) and a bending structure (3); the outer protective structure (1) is a concave structure and one side with an opening is placed vertically; the inner mass block (2) is arranged on the side of the outer protective structure (1) close to the vertical inner wall, the inner mass block (2) is connected with the bending structure (3) only at the top close to the side with the opening of the concave structure; the bending structure (3) is arranged on the side of the outer protective structure (1) close to the opening, the bending structure (3) includes shaped structures (18) vertically spliced, a top vertical beam (12) and a top transverse beam (13).
