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 tuned liquid damper combining liquid damping and liquid column damping, comprising a water tank, a baffle plate, a baffle plate fixing and adjusting device, an elastic support and a transfer device. The invention combines the advantages of a tuned liquid damper (TLD) and a tuned liquid column damper (TLCD), not only ensures simple manufacture, wide application, but also enhances the damping and shock absorption effect. The present invention takes a rectangular deep water tank as a basic model, and sets hinged joints in the middle of the bottom of the water tank, and uses elastic supports at both ends; a vertically placed flat plate is set in the center of the water tank, and the length of the deep water tank that penetrates into the liquid in the tank is adjustable. When the wind load or earthquake load acts, the liquid in the water tank not only vibrates in the horizontal direction, but also produces a change in the liquid level in the vertical direction, thereby increasing its vibration energy consumption. The damping ratio of the liquid damper can also be adjusted by adjusting the height of the plate and changing the flow state of the liquid.

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...
