The invention discloses a composite low-yield-point metal damper with a multi-dimensional energy dissipation function. The composite low-yield-point metal damper is arranged in an interlayer support, aims to play a role in energy dissipation and shock absorption in any direction in a plane, and simultaneously has vibration damping and resetting functions in the vertical direction and the torsion direction. The damper consists of a bending energy-dissipation damper, a shearing energy-dissipation damper, an inner steel cylinder, an outer steel cylinder, an outer steel ring and a steel plate, and is characterized in that the inner steel cylinder, the outer steel cylinder and the outer steel ring are coaxial, the bending energy-dissipation damper and the shearing energy-dissipation damper are horizontally and symmetrically arranged along the radial direction of the circumference of the steel cylinder, two ends of the bending energy-dissipation damper and the shearing energy-dissipation damper are respectively fixed on the inner steel cylinder and the outer steel cylinder, one side of the outer steel cylinder is welded, one side of the inner steel cylinder is welded, the outer steel cylinder and the outer steel ring are coaxial, the steel plates are horizontally and symmetrically arranged in the radial direction of the circumference and fixed in a welding mode, and the two ends of each steel plate are fixed to the outer steel cylinder and the outer steel ring respectively. According to the composite low-yield-point metal damper, deformation, energy dissipation and shock absorption can be carried out in any direction in a plane, in the vertical direction and in the torsion direction, the yield strength is low, and the energy dissipation efficiency is high.
