The utility model discloses a beam-falling-prevention vibration reduction and isolation spherical sectional steel support seat, which comprises an upper support seat plate, a lower support seat plate, a spherical concave lining plate and a spherical lining plate, wherein the spherical concave lining plate is arranged under the upper support seat plate, the spherical lining plate is arranged above the lower support plate and is matched with the spherical concave lining plate, a spherical surface slide plate is arranged between the spherical concave lining plate and the spherical lining plate, and a sliding friction energy dissipation pair is arranged between the spherical lining plate and the lower support seat plate. The beam-falling-prevention vibration reduction and isolation spherical sectional steel support seat is mainly characterized in that a beam-falling-prevention device is arranged between the upper support seat plate and the lower support seat plate, the beam-falling-prevention device comprises a slide sleeve and two pull rods, one ends of the pull rods are respectively hinged to the upper support seat plate and the lower support seat plate, and the positions of the other ends of the pull rods are glidingly limited in a cavity of the slide sleeve. The beam-falling-prevention vibration reduction and isolation spherical sectional steel support seat has the beneficial effects that in a non-earthquake state, the beam-falling-prevention vibration reduction and isolation spherical sectional steel support seat has all functions of an ordinary spherical support seat; when a rare occurrence earthquake occurs, the displacement of the sliding friction energy dissipation pair can exceed the design value, at the moment, the beam-falling-prevention device takes an effect, the further displacement of the support seat is prevented, and the beam falling danger due to the falling of the beam from a lower part structure support is avoided.
