There is therefore a need for an additional vibration control device to reduce the acceleration response and improve human comfort.
Tuned Mass Dampers (TMD) are widely used for controlling wind vibration and vibration in skyscrapers, large-span bridges, critical equipment, etc. The current conventional TMD consists of a mass vertically supported by wire rope suspensions or springs and assisted by liquid dampers, and is a passive device that moves with structural vibrations (following building swings or following deck vertical vibrations). However, TMD is made of all steel, most parts require precision machining, and is expensive to manufacture and complex to install. The TMD cost of the general 500-ton motion quality is about 2000-2500 ten thousand yuan. In addition, in the long-term use of TMD, the liquid damper providing damping is easy to leak due to abrasion, and is inconvenient to repair and replace due to the volume and weight.

Example 5:
this embodiment is based on the structure scheme illustrated in embodiment 1, and details one of the practical manufacturing schemes of the tuned liquid mass damper (TSD) are as follows; the structure includes: a top cover, a box body and a liquid damping device. During the design of the TSD, H-shaped steel is preferably used as a main bearing component, channel steel is used as an auxiliary bearing component, and a thin steel plate is combined to manufacture a top cover, a box body and a bottom plate of the TSD, the joints of the steel plate and the shaped steel are full weld joints, and waterproof and antirust coatings are coated on the inner wall and the outer wall of the TSD. The basic frequency of the super high-rise building is matched through the design of the horizontal plane size of the TSD and the height of the water level. The water level is monitored by a water level meter. The top cover, the box body and the bottom plate are made of steel plates, are easy to install and maintain, and can also be made of reinforced concrete, but the waterproof treatment needs to be paid attention to.
The TSD is internally provided with liquid damping devices, the number of the damping devices is changed according to specific items, and nine damping devices are generally arranged as shown in FIG. 1. The liquid damping device is manufactured by using a high-damping steel plate, and under one embodiment, the liquid damping device is connected with the TSD top cover and the TSD bottom plate through bolts at the upper end and the lower end respectively, and the liquid damping device body is designed to be cross-shaped so as to adapt to water movement in two horizontal main directions. A wing plate for width adjustment is added on the liquid damping device body, and the wing plate is fixed on the body by a bolt; in one embodiment, the wing plate is provided with a transverse sliding groove. The overall width is adjusted to provide different damping ratios to the TSD by adjusting the different positions at which the wings move along the transverse chute to achieve different TSD performance requirements. The liquid damping device is made of high-damping steel plates, so that the service life can be greatly prolonged, and low-cycle fatigue is not easy to generate. The joints of the liquid damping device, the top cover and the bottom plate are full weld joints, and the whole and the welded joints are coated with waterproof and antirust paint.
When TSD is used as fire water tank simultaneously, need to set up access hole and steel cat ladder in order to overhaul, need set up pipeline flange interface in the bottom and be used for connecting the fire control pipe network, need set up the water inlet at the top and be used for replenishing the fire-fighting water, need set up the fluviograph in order to monitor the water level height. The TSD also can be used as a damping device independently instead of being used as a fire water tank. Still need set up access hole and steel cat ladder so that overhaul this moment, set up the fluviograph in order to monitor the water level height, need not to set up flange interface and water inlet.
