Energy consumption support device with replaceable frames

Abstract

The invention provides an energy consumption support device with replaceable frames. The energy consumption support device comprises a frame structure and a middle connecting part, wherein the inner side of the frame structure is provided with at least three frame end lug plates, the middle connecting part is arranged in a polygon which is defined by the at least three frame end lug plates, a replaceable energy consumption support unit is connected between the middle connecting part and each frame end lug plate, and each replaceable energy consumption support unit comprises an end part damper, a steel tie rod and a middle part damper, wherein the end part damper, the steel tie rod and the middle part damper are connected. When an earthquake action happens, the dampers of the energy consumption support device can largely absorb, consume and store input energy of earthquake motion, and the earthquake action is dramatically reduced. By means of the energy consumption support device with the replaceable frames, the problem of shock absorbing of a multi-story frame structure is solved, the purpose that the shock absorbing is provided for the multi-story frame structure which must need shock absorbing to guarantee that the multi-story frame structure is safe under the earthquake loading function is achieved, and quick dismantling and replacing can be achieved after earthquake.

Description

technical field [0001] The invention relates to the field of shock-absorbing and energy-dissipating multi-story frames, in particular to an X-shaped energy-dissipating support device with replaceable frames. Background technique [0002] China is located between two major seismic belts - the Eurasian seismic belt and the circum-Pacific seismic belt, and is one of the countries most severely affected by earthquakes in the world. Historically, strong earthquakes of magnitude 6 or above have occurred many times in the Yangtze River Delta and the Pearl River Delta. In the Beijing-Tianjin-Bohai Rim region, in the past 300 years, an average of 7 magnitude or more earthquakes have occurred every 44 years. With the acceleration of urbanization, a large amount of national wealth is rapidly concentrated in cities and urban agglomerations. And more than one-third of my country's built or planned urban agglomerations are located in areas where major earthquakes of magnitude 7 or above ...
