Three-dimensional tuned mass damper

Abstract

The invention provides a three-dimensional tuned mass damper and relates to a vibration control device for a building structure. The three-dimensional tuned mass damper comprises a horizontal crosswise mass block, a horizontal longitudinal mass block, an upright mass block, a horizontal crosswise viscous damper, a horizontal longitudinal viscous damper, and the like. An outer frame of the device is formed into a square by structural steel; an upright hoisting frame is a regular pyramid made of structural steel through welding and is fixed on the outer frame of the device; a horizontal crosswise mass block guide rail and a horizontal longitudinal mass block guide rail are arranged in a cross form; the horizontal crosswise mass block and the horizontal longitudinal mass block, the horizontal crosswise viscous damper and the horizontal longitudinal viscous damper, and springs are respectively and symmetrically arranged on the guide rails; and the longitudinal mass block, the longitudinal viscous damper and the spring are mounted on the longitudinal mass block guide rail along an upright direction. The three-dimensional tuned mass damper is uniformly, stably and effectively stressed under the actions of wind vibration and earthquake, is suitable for important structures such as high-rise and towering buildings and nuclear power stations, and is capable of reducing the earthquake response of the building structure and effectively protecting the building structure.

Description

technical field [0001] The invention relates to a building structure vibration control device, in particular to a three-dimensional tuned mass damper for building structure vibration control. Background technique [0002] The tuned mass damper (TMD for short) system is to add inertial mass on the top layer of the structure, and connect with the main structure with springs and dampers, and apply the principle of resonance to control a certain vibration mode of the structure. Usually the inertial mass can be a water tank, a machine room or a revolving restaurant in a high-rise or towering structure. The mechanism of its vibration control on the structure is: the dynamic characteristics of the original structure system change due to the addition of TMD. It also plays the role of energy dissipation, so as to achieve the purpose of significantly attenuating the vibration response of the original structure. [0003] The earliest source of modern ideas for the structural applicat...

[0007] However, the environmental loads such as wind and earthquakes on the building structure come from different directions. The traditional TMD cannot control the wind vibrations and earthquakes in different directions. Therefore, it is necessary to develop a method that can control wind vibrations and earthquakes in different directions. TMD, so the traditional TMD can't do anything
