High energy consumption damping wall

Abstract

The invention discloses a high energy consumption damping wall, and belongs to the technical field of high-rise structure vibration reduction. The high energy consumption damping wall comprises damping plate outer frames, damping plates, and a T-shaped structure; the damping plate outer frames are fixed to a lower floor slab; the multiple damping plates are arranged in the damping plate outer frames, and working chambers formed in the positions, between the adjacent damping plates, in the damping plate outer frames are filled with shear thickening fluids (STF) correspondingly; the horizontal part of the T-shaped structure is fixedly connected with an adjacent last floor structure, the lower vertical part of the T-shaped structure penetrates into the damping plate outer frames and the damping plates, the end of the T-shaped structure is connected to the bottom edges of the damping plates, and the two sides of the T-shaped structure are connected with the damping plates and the damping plate outer frames respectively; a plurality of shear mechanisms are arranged in the damping plates, one ends of the shear mechanisms are fixedly connected with the T-shaped structure, the other ends of the shear mechanisms are directionally hinged to the damping steel plates, and the shear mechanisms are arranged parallel to the plate surfaces of the damping plates; and when a high-rise structureproduces shaking, power of adjacent floors is amplified by the shear mechanisms, the damping plates squeeze the STFs at the high rate, the shear thickening properties of the STFs are excited, high damping force is produced instantaneously, and external input energy is consumed.

Description

technical field [0001] The invention belongs to the technical field of vibration reduction of high-rise structures, in particular to a high-energy-consuming damping wall. Background technique [0002] Since the 1980s, with the continuous deepening of reform and opening up, high-rise buildings have also developed. High-rise residential buildings provide a guarantee for the rapid increase of urban population. Therefore, in the central areas of large and medium-sized cities, it is imperative to build high-rise buildings. [0003] In the United States, the development of high-rise buildings has matured, while the golden period for the development of high-rise buildings in my country was the 1980s and 1990s. Both the quality and quantity of high-rise buildings have developed rapidly. For example, the Shanghai Jinmao Tower in 1998 had 88 floors and a height of 420 meters; the CITIC Plaza built in Guangzhou in 1996 had 80 floors and a height of 391 meters. Since then, the enthusi...

Problems solved by technology

[0006] Aiming at the problem that the traditional viscous damping wall has constant and limited damping force on the upper part of high-rise buildings when wind or earthquake occurs, the present invention provides a high-energy-consuming damping wall, which uses a scissor mechanism to amplify the dynamic force between adjacent floors Response, make it stimulate the shear thickening mechanism of STF, generate high damping force instantly, thereby consume external energy, because STF has the characteristics of instantaneous response, high energy consumption, process reversibility and no external energy input, etc., therefore, the present invention has Intelligent, fast response, high energy consumption, etc.
