The invention relates to a horizontal type vertical eddy current tuned mass damper. The horizontal type vertical eddy current tuned mass damper comprises a bottom plate, adjusting mass blocks, fixed mass blocks, a vertical support plate, plate springs, a copper plate assembly and magnets, wherein the vertical support plate is welded to the middle of the bottom plate; the two parallel plate springsare connected to the upper end of the vertical support plate; the fixed mass blocks are connected and symmetrically distributed at two ends of the plate springs; the adjusting mass blocks are connected onto the fixed mass blocks and used for adjusting vibrational frequency of the damper; the copper plate assembly is vertically arranged in the center of the two parallel fixed mass blocks equippedwith the magnets, a gap is reserved between a magnet assembly and the copper plate assembly, and a projection area of each magnet on the copper plate assembly is changed by moving the copper plate assembly, so that damping ratio of the damper is adjusted. Compared with the prior art, the horizontal type vertical eddy current tuned mass damper has the advantages of adjustable damping and rigidity,high energy-dissipating capacity, stable performance, simple and convenient operation, low cost and the like.
