Abstract
The invention provides a bidirectional multi-frequency rectangular lattice type tuned liquid damper and relates to a building structure shock controlling device. The bidirectional multi-frequency rectangular lattice type tuned liquid damper is formed by a rectangular-section container, a lattice plate, in-built solution and a fixed part. The damper is simple, practical, convenient to maintain, low in cost, suitable for use in a short term and in a long term, good in self-activation, small in required space, simple to install and convenient to use. The transverse and longitudinal earthquake reactions are controlled by adjusting transverse and longitudinal dimensions, the earthquake reactions under the effects of different formations can be controlled by adjusting the transverse dimension of a lattice, and the fact that a tuned liquid damper designed according to natural vibration frequency of a high-order structure is tall and narrow is avoid. The amount of the dampers is increased correspondingly according to increase of formation orders so as to improve sensitivity of controlling of high-order formation wind vibration and earthquake reactions. When meeting with an earthquake or strong wind, the bidirectional multi-frequency rectangular lattice type tuned liquid damper can reduce power reaction of a building structure and has good protecting effect on the building structure.
Description
Technical field
The present invention relates to a kind of building structure vibrations control device, particularly relate to a kind of bidirectional multi-frequency rate rectangle lattice Tuned Liquid of building structure vibrations control.
Background technology
The seismic design basic thought of " ductility structural system " is generally adopted in China and countries in the world at present.This Aseismic Structure System; Damaging appears in earthquake in admissible structure and supporting member (post, beam, node etc.); Promptly rely on the damage of structure and supporting member to consume most of energy; Often cause structure heavy damage even collapse in earthquake, this be to a certain extent unreasonable also be unsafe.U.S. mat scholar Yao Zhiping of Chinese origin (J T P Yao) professor combined modern control theory to propose the notion of vibration control of civil engineering structure first on forefathers' basis in 1972, thereby had started the new situation of structural vibration control.China structural vibration control is extensively paid attention at first proposes the control beginning of shaking of tall and slender structure wind Wang Guang academician far away in 1980, has promoted from then on that China's structural vibration control is theoretical, technology and application and development.Structural vibration control can alleviate reaction and the damage accumulation of structure under dynamic actions such as earthquake, wind, vehicle, wave, stream, ice effectively; The shock resistance that improves structure effectively with combat a natural disaster performance, be active and effective method of civil engineering structure protection against and mitigation of earthquake disasters and technology.
Along with highrise building develops to the direction of large ratio of height to width and light-weight high-strength material day by day, the rigidity of structure and damping constantly descend, and be more and more responsive to soakings such as wind, earthquakes.Structural vibration control more and more comes into one's own as a kind of economy, effective means in recent years.Be provided with life or fire water box on the highrise building mostly, earthquake and the wind that the Tuned Liquid that can utilize these waterbox design to become the is used for high-level structure control of shaking.But TLD comes with some shortcomings, and at first, Tuned Liquid generally only is used for single vibration shape control, can not carry out many vibration shape controls effectively.The second, earthquake is multidirectional, and the horizontal and vertical natural frequency of structure also is different, needs to solve the problem of Tuned Liquid to different directions and different frequency earthquake control.The 3rd, need to solve according to the Tuned Liquid of high-order natural frequency of structures design not only high but also narrowly, do not have a problem of engineering operability.The 4th; Design multiple Tuned Liquid for controlling multistage earthquake response; Number too much causes quality excessive, and its putting position also receives the restriction of building function and requirement attractive in appearance, not only has certain difficulty and unreasonable economically with in the construction; And to living water use, especially water for fire brings difficulty.The 5th, different buildings have demands of different to Tuned Liquid, and factory is produced in batches has certain influence.Therefore the present invention mainly addresses the above problem, and can control the Tuned Liquid of different buildings, different directions, different formations, not only controls the effective of earthquake, and is convenient to life and water for fire operation, and good looking appearance is convenient to produce in batches.Earthquake and the wind that Tuned Liquid both can be used for the new construction structure shake the control design also can be used for existed building the reinforcing maintenance, transform, have good economic benefit.
Summary of the invention
The object of the present invention is to provide a kind of bidirectional multi-frequency rate rectangle lattice Tuned Liquid; Be installed on top of high-rise buildings; What not only can be used to highrise building provides fire-fighting and living water use; The wind that also can be used for highrise building shakes and Seismic Response Control, improves the comfort level and the degree of safety of building.The present invention controls horizontal and vertical earthquake response through adjusting horizontal and vertical size; The mode of lattice adopts and does not wait dividing method, through adjustment lattice lateral dimension, makes its earthquake that not only can control different directions, and can control the earthquake response under the different formation effects.
