Abstract

The invention discloses a rocker bearing water tank damper, and belongs to the technical field of energy dissipation and vibration attenuation of civil engineering structures. The rocker bearing water tank damper comprises a plurality of rocker sliding support saddles, a water tank, a damper support saddle, a box column, and a viscous damper; each rocker sliding support saddle comprises an upper support saddle plate, a metal ball and a lower support saddle plate; the upper support saddle plate is fixed at the lower surface of the water tank; the lower support saddle plate is fixed on an upper top plate or a spandrel girder of the structure; the upper saddle plate is opposite to the lower saddle plate; the metal ball is placed in the middle to achieve oppositely sliding between the upper support saddle plate and the lower support saddle plate; the box column is arranged at the bottom part of the water tank; the damper support saddle is arranged on the upper top plate or the spandrel girder of the structure; and the viscous damper is horizontally arranged between the box column and the damper support saddle. By adopting the rocker bearing water tank damper, on one hand, the adverse effect of a high-level water tank on the structure under the horizontal load is removed; and on the other hand, dynamic response of the structure under the horizontal load is greatly reduced by the formed water tank damping system. The rocker bearing water tank damper is stable in damping effect, simple in structure, safe and reliable, good in durability, and strong in designability.

Description

technical field

[0001] The invention belongs to the technical field of energy dissipation and vibration reduction of civil engineering structures, and in particular relates to a water tank damper for a pendulum support that uses a water tank on the top of a high-rise building to control building vibration and reduce structural response under wind load and earthquake load. Background technique

[0002] For high-rise buildings, due to the needs of life, production, fire protection, etc., it is often necessary to install a water tank on the top of the structure. The mass of the water tank usually exceeds tens of tons or even hundreds of tons, and the ordinary installation method will greatly enhance the vibration response of the structure under horizontal load, which is very unfavorable for the vibration reduction and earthquake resistance of the building. On the other hand, in recent years, the mass-tuned damper has been widely used as an energy dissipation and vibration reduc...
