Description

Two-way horizontally adjustable tuned mass damper

technical field

The invention relates to a two-way horizontally adjustable tuned mass damper.

Background technique

With the development of economy and society, the development trend of materials in high-rise buildings is lightweight and high-strength materials, but the large number of applications of these materials leads to the relative reduction of stiffness and damping of high-rise buildings. When an earthquake occurs, the seismic response of the building (such as top displacement, bottom axial force, etc.) is too large, which affects the safe and stable operation of tall buildings, causes serious damage to the building, and even collapses, causing huge economic losses. The tuned mass damper is a classic shock-absorbing control device that generates vibrations during an earthquake and drives the tuned mass damper to vibrate together. The inertial force generated by the relative motion of the tuned mass damper reacts on the building to reduce the structural vibration response. The current tuned mass dampers are all shock absorbers. Multi-directional shock absorption requires the installation of multiple tuned mass dampers, which increases the burden on the building, and the frequency of each direction is different, so the shock absorption effect is not good.
