Description
Technical Field
The invention belongs to the technical field of high-rise structure vibration reduction, and particularly relates to a high-energy-consumption damping wall.
Background
In the last 80 s, as reforms open and goes deep, high-rise buildings have also been developed. High-rise residential buildings provide guarantee for the rapid population increase of cities, so that the construction of high-rise buildings becomes imperative in the central areas of large and medium-sized cities.
In the united states, the development of high-rise buildings is mature, and the golden period of the development of high-rise buildings in China is the last 80-90 th century, and the quality and the quantity of the high-rise buildings are rapidly developed. Such as the Jin Mao building in Shanghai in 1998, 88 floors, up to 420 meters; the middle school square built in Guangzhou 1996 has 80 layers and a height of 391 meters. After that, the heat of high-rise building construction in China is always high, and the construction sites are spread to small and medium-sized cities. According to statistics, the world has 106 seats which are more than 200 meters in high-rise buildings in 2015, wherein, the China is built with 62 seats, which account for more than half of the total number; this is sufficient to illustrate the violent development of high-rise buildings in our country.
With the continuous development of high-rise buildings, ensuring the life and property safety of residents in the high-rise buildings is an unavoidable problem when earthquake or wind vibration occurs. Vibration damping technology under high-rise buildings has become a popular research field in recent years in the civil engineering discipline. At present, compared with the traditional anti-seismic and wind-resistant reinforcement technology, the energy dissipation and vibration reduction technology applied to the high-rise structure has the advantages of being safer, more economical and more reasonable in technology, and is widely applied to the high-rise structure. The vibration damping technology is an important way for shock resistance and wind resistance, has been well applied in developed countries such as Japan in recent years, and has yet to be developed deeply in China. The research directions are roughly divided into three: basic vibration isolation, passive energy consumption vibration reduction and semi-active control. Among them, the passive energy-consuming vibration damping technique is the most effective vibration damping technique at present. These damping techniques mainly include: viscous damper, viscoelastic damper, viscous damping wall, viscoelastic damping wall, friction damper, tuned mass damper, etc. The viscous damping wall is favored because of the thin thickness and obvious damping effect, and the appearance of the viscous damping wall meets the building requirements. However, the traditional viscous damping wall has the defects of incapacity of damping materials, insufficient damping strength and the like.
Shear thickening fluids (SHEAR THICKENING fluid, STF) have received increasing attention from researchers as an emerging smart material. The shear thickening fluid consists of a dispersing agent and a disperse phase, wherein the dispersing agent is a polar solvent, such as: ethylene glycol, polyethylene glycol, and the like; the dispersed phase is a micro or nano scale particle, such as: silica, and the like. Under normal conditions, STF is in a liquid state, and under proper shearing action, the viscosity of STF can rise rapidly with the increase of external shearing rate, the rise of viscosity can reach several orders of magnitude, under the action of high-speed external load, STF can be converted into a solid-like or even solid state, and the process is reversible. Meanwhile, the STF has the characteristics of reversible process and quick response.
