Abstract

The invention relates to a tuned mass damper. A lamination support component is fixedly arranged at the inner bottom of a steel cylinder; a mass block component is fixedly arranged at the top of the lamination support component; the upper part of the mass block component is connected with the inner wall of the steel cylinder through a spring; the elastic lamination support component is fixedly connected to the inner bottom of the sealed steel cylinder to serve as a frequency generating mechanism; the mass block component is fixedly connected to the top of the lamination support component to serve as a shock-damping mass block. A clearance between the lamination support component and the mass block component is fully filled with energy-consuming liquid to generated damp, so that the operation mechanism and the aim of the tuned mass damper can be realized , the change of the natural vibration frequency of the tuned mass damper can be realized by changing the heights, the areas and the numbers of steel plates and rubber layers, the change of the vibration mass of the tuned mass damper can be realized by changing the numbers, the thicknesses and the areas of the mass plates, and the change of damping ratio can be realized by changing the viscidity of the energy-consuming liquid.

Description

technical field [0001] The invention belongs to the technical field of energy dissipation and shock absorption of civil engineering structures, and in particular relates to a mass-tuned damper for controlling the vibration of a building and reducing the structural response of the structure under the action of wind load and earthquake load. Background technique [0002] For high-rise high-rise structures, the control of lateral deformation of structures under wind loads and earthquake loads has received extensive attention and attention. It has been proved by a lot of practice that the mass tuned damper is a very effective vibration control device. It can be installed in a suitable position of the structure, and through the reasonable setting of lateral stiffness, mass block and damping parameters, it can greatly reduce the The lateral vibration displacement amplitude of the structure, and correspondingly reduce the horizontal shear force on the vertical members of the struct...
