Abstract

The invention relates to a tuned mass damper for controlling tri-dimensional translation and horizontal torsion of a building structure and a manufacturing method thereof, belonging to the technical field of structural engineering seismic resistance and shock absorption. The damper comprises two tuned mass blocks which move along the two horizontal axis directions of the building structure, horizontal viscous dampers connected with the tuned mass blocks, universal rolling spherical hinges arranged at the bottom of the tuned mass blocks, limit baffles connected with the horizontal viscous dampers, horizontal clapboards, torsion mass blocks, torsional levers, torsion shafts, torsion fixed shafts, torsional damper springs and vertical viscous dampers arranged at the bottom of the horizontal clapboards. The tuned mass damper for controlling tri-dimensional translation and horizontal torsion of a building structure can perform tuned energy dissipation shock absorption in the two horizontal directions, vertical direction and horizontal torsional direction of the structure.

Description

technical field [0001] The invention relates to a damper for controlling bidirectional horizontal, vertical and torsional vibrations of a building structure by relying on horizontal movement and rotation in a plane of a tuning mass and a manufacturing method thereof, belonging to the technical field of anti-seismic, anti-shock and wind resistance of structural engineering . Background technique [0002] The ground motion during an earthquake is a complex multi-dimensional motion, including three translational components and three rotational components. The multidimensional characteristics of earthquake motion determine that the dynamic characteristics of building structures under earthquakes are also multidimensional, including both horizontal and vertical deformations, as well as torsional and swaying deformations. The causes of torsional vibration are: first, there is a rotational component in ground motion, or there is a phase difference in the motion of various points o...
