Embodiment 1

[0026] Example 1: figure 1 is the front view of the present invention, figure 2 A top view of the invention. It can be seen from this figure that the structure includes a baffle 1 , a baffle fixing and adjusting device 2 , a water tank 3 , a bottom elastic support 4 , a bottom hinge device 5 and a water body 6 . Wherein, the section of the baffle 1 is rectangular, and the upper end is opened at a certain distance to realize the installation and use of the baffle fixing and adjusting device 2 . The baffle plate fixing and adjusting device 2 is made up of screws, nuts and fixtures, which can adjust the depth that the baffle plate 1 extends into the liquid in the water tank 3 . Different buildings and different load situations can be adapted by adjusting the depth of the baffle plate 1 into the liquid surface. The upper part of the water tank 3 is closed, and a gap is reserved in the center of the top plate to install a baffle plate. The body of water 6 oscillates in the ta...

Abstract

The invention relates to a novel TLD which combines liquid damping and liquid column damping. The novel TLD comprises a water tank, a baffle, a baffle fixing and adjusting device, elastic supports and a hinge device. The novel TLD combines the advantages of a TLD and a TLCD (Tuned Liquid Column Damper), is simple manufacturing and multi-purpose and can improve damping and shock-absorbing effects. According to the novel TLD, the rectangular deep water tank is utilized as a basic model, the middle of the bottom of the water tank is hinged and fixed, and two ends of the bottom of the water tank are provided with the elastic supports. The center of the water tank is provided with the vertically-arranged flat plate, and the length of the flat plate in the liquid inside the tank is adjustable. When wind loads or earthquake loads are in action, liquid in the water tank can generate vibration in a horizontal direction and can also generate liquid level change in the vertical direction, and accordingly the vibration energy loss of the liquid can be increased. The flow condition of the liquid can also be changed by adjusting the height of the flat plate so as to adjust the damping ratio of the liquid damper.

Description

technical field [0001] The invention relates to a novel tuned liquid damper combining liquid damping and liquid column damping, which combines the advantages of tuned liquid damping and tuned liquid column damper, and effectively improves the damping effect of the damper. The invention belongs to the field of vibration control of civil structures. Background technique [0002] In recent years, with the continuous and in-depth research on the structure's earthquake resistance and disaster reduction, the new type of damper has gradually attracted people's attention. Among them, the tuned liquid damper (TLD) has been used more and more because of its economy, convenience, wide application and good damping effect; the tuned liquid column damper (TLCD) has gradually been paid attention to because of its remarkable damping effect . By adjusting the natural frequency, the TLCD system can generate damping force and weaken the dynamic response of the building body through the move...
