Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] Please refer to figure 1 and figure 2 , the tuning liquid damper provided by the embodiment of the present invention includes a water tank 1 and a liquid 2 located in the water tank 1, the water tank 1 is a shallow water tank, and the water tank 1 is a cylindrical water tank with a large upper opening and a smaller lower opening, that is, in the present invention The water tank is an inclined wall type water tank.

[0023] The shock absorption principle of the tuned liquid damper (TLD) is: when the TLD is installed on the structure, the structure is subjected to external excitation and vibration will cause the water tank to shake together, thereby arousing the water in the water tank to slosh, and the sloshing water body produces dynamic water pressure. On the side wall of the water tank and transmitted to the structure, so ...

Abstract

The invention relates to the technical field of seismic prevention and seismic prevention of high-rise buildings. The tuned liquid damper comprises a water tank and liquid in the water tank, and the water tank is designed into a shallow columnar water tank with a large upper opening and a small lower opening, namely the water tank is an inclined-wall water tank. Compared with a common box type TLD (tuned liquid damper) in the prior art, the tuned liquid damper has the advantages that due to soft spring characteristics of the inclined-wall TLD, a larger damping force can be generated in use of liquid equal in quantity, and utilization efficiency of the liquid in the water tank is improved. The cylindrical inclined-wall TLD is capable of better adapting to arbitrariness of load directions to play a role in damping in all directions, so that the cylindrical inclined-wall TLD can be better applied to buildings, such as round buildings and square buildings, approximately uniform in direction.

Description

technical field [0001] The invention relates to the technical field of shockproof and high-rise structural buildings, in particular to a tuned liquid damper suitable for wind vibration and earthquake response control of high-rise structures in civil engineering. Background technique [0002] The tuned liquid damper (Tuned Liquid Damper, referred to as TLD) uses the dynamic lateral force generated by the liquid in the fixed water tank during the sloshing process to provide shock absorption. Because of its low cost, easy installation, less maintenance, good automatic activation performance, easy to match frequency modulation and many other advantages, it has been widely used in the field of civil engineering vibration control at home and abroad. The tuned liquid damper can be divided into deep water TLD and shallow water TLD according to the ratio of the water depth to the length of the tank in the vibration direction. Although the deep water tank can be refitted with the liv...
