AI Technical Summary
The connected super-high-rise buildings will produce a large wind vibration response under the action of strong winds. The existing dampers such as TMD and TLD are limited by mass and volume, and their control effect decreases with the changes in the structure's self-vibration frequency and damping.
An inertial capacity-tuned liquid damper is designed, including a water tank, inertial capacity element, linear spring and damping element. Through the cooperation of inertial capacity element and water tank, the energy generated by the building is consumed by the inertial effect and damping effect, and partially flexible connection is achieved through the design of sliding support and rollers, reducing overall torque damage.
Compared with traditional control devices, the inertial volume-tuning liquid damper occupies less space and mass, which can effectively reduce wind vibration response and reduce overall torque damage in earthquakes or strong winds. At the same time, the water in the water tank can be used for fire fighting water.

Abstract
Description
Technical Field
[0001] The utility model belongs to the field of wind vibration control of connected super high-rise buildings, and specifically relates to an inertia capacity-tuning liquid damper. Background Art
[0002] With the rapid development of social economy, conjoined super high-rise buildings have emerged. As a complex type of high-rise buildings, conjoined super high-rise buildings not only have beautiful architectural appearance and save the land area required for construction, but also the connection between conjoined super high-rise buildings can provide a broad sightseeing view. Therefore, its architectural form has been widely used. However, for conjoined super high-rise buildings, the corresponding conjoined super high-rise buildings have large flexibility and small damping, which will produce a large wind vibration response under strong wind. In order to solve this problem, many scholars have proposed different control devices to control the wind vibration response of conjoined super high-rise buildings, such as tuned mass damper (TMD), tuned liquid column damper (TLD), multiple tuned mass damper (MTMD), etc. At present, the control effect of passive control devices such as TMD and TLD, which are traditional dampers used to control conjoined super high-rise buildings, depends on their mass. For conjoined super high-rise buildings, the space cost of the top floor is high, which limits the application of control devices with large mass and volume in structural wind resistance. TMD only has a control effect on vibrations near specific frequencies and has the characteristics of frequency tuning sensitivity. During the actual use of connected super high-rise buildings, the natural frequency and damping of the connected super high-rise building structure may change over time, resulting in a significant decrease in the control effect of TMD. Since the vibration reduction effect of TLD depends on the shaking of the liquid, the water tank volume of the TLD occupies a large area, and it also increases the load of the building structure, thereby bringing a certain burden to the building's bearing capacity. Moreover, for connected super high-rise buildings, most of their corridors are fully rigidly connected. When the structural corridor adopts a rigid connection, the corridor part of its building structure is prone to overall torque damage under the action of an earthquake. For example, patent CN104294955A discloses a dual-tuned liquid column damper, which, when used in connected high-rise buildings, needs to be installed in two buildings of the connected building, which occupies a large area and cannot effectively reduce the wind vibration response.

[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.
[0017] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.
[0018] It should be noted that in the description of the present invention, the orientation or position relationship indicated by the term is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
[0019] In the description of the present utility model, unless otherwise clearly stipulated and limited, the terms "installed", "provided with", "sleeved / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection. It can be a mechanical connection or an electrical connection. It can be a direct connection or an indirect connection through an intermediate medium. It can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood according to specific circumstances.
[0020] In addition, in the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.
[0021] like Figures 1 to 4 As shown, an inertia-tuned liquid damper comprises:
[0022] A water tank 5, one end of which is fixedly connected to an inertia element 6, the other end of which is fixedly connected to a linear spring 7 and a damping element 8, the inertia element 6 is fixedly connected to a corridor 3, a sliding support 4 is fixedly connected under the corridor 3, one end of the corridor 3 is fixedly connected to a building floor 9 of a connected super high-rise building A1, the other end of the corridor 3 is slidably connected to a connected super high-rise building B2 through the sliding support 4, the water tank 5 is slidably connected to the connected super high-rise building B2, and the linear spring 7 and the damping element 8 are fixedly connected to the building floor 9 of the connected super high-rise building B2.
[0023] Working principle: When the connected super high-rise buildings A1 and the connected super high-rise buildings B2 are subjected to strong winds and their building structures produce wind vibration responses, the connected super high-rise building A1 first transmits the acceleration generated by the vibration to the sliding support 4 through the corridor 3, and then transmits it to one end of the inertia element 6 through the sliding support 4. Since the other end of the inertia element 6 is connected to the water tank 5, a relative acceleration will be generated at both ends of the inertia element 6, and a mass amplification effect will be generated through the inertia element 6. Its energy will be transferred to the water tank 5 through the other end of the inertia element 6, and then the inertia generated by the water tank 5 will be used to consume energy. The damping element 8 and the linear spring 7 will also generate damping to hinder the movement of the water tank 5, thereby consuming the energy of the system in the form of negative work.
[0024] In the above technical solution, a roller I41 is further provided under the sliding support 4, and the sliding support 4 is slidably connected to the connected super high-rise building B2 through the roller I41. A roller II51 is further provided under the water tank 5, and the water tank 5 is slidably connected to the connected super high-rise building B2 through the roller II51.
[0025] When the building structure vibrates, the sliding support 4 and the roller Ⅰ41 can coordinate the displacement between the two super-high-rise connected buildings and the corridor 3, and can better transmit the relative acceleration to the inertia element 6. The corridor 3 can be used as a fire escape for the connected super-high-rise buildings or as a sightseeing corridor, leisure tea room and other daily traffic and sightseeing uses. The roller Ⅱ51 helps the water tank 5 to sway left and right in response to wind vibration.
[0026] In the above technical solution, the water tank 5 is U-shaped and contains liquid 11. The liquid 11 in the U-shaped water tank 5 has different heights on both sides when shaking, thereby generating a pressure difference, and when the building responds to wind vibration, its energy can be dissipated.
[0027] In the above technical solution, a hole door 10 is arranged in the water tank 5, and the hole door 10 is mesh-shaped or grille-shaped. The hole door 10 increases the damping ratio of the water tank 5, plays a role in increasing the internal damping force of the water tank 5, thereby reducing the frequency of shaking of the liquid 11 in the water tank 5.
[0028] In the above technical solution, the liquid 11 may be pure water, so that it can be used as fire-fighting water for buildings later.
[0029] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and implementation modes. It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the utility model is not limited to the specific details and the illustrations shown and described herein.
