Magneto-rheological damping tuned damper for super-high-rise buildings

Abstract

The invention discloses a magneto-rheological damping tuned damper for super-high-rise buildings. The magneto-rheological damping tuned damper for the super-high-rise buildings mainly comprises a magneto-rheological tuned mass block, a leaded steel lamination damper, a rigid force transmitting plate, a floor embedded steel plate, a field regulator, a floor and a building main body framework. The magneto-rheological tuned mass block is adopted as a variable-damping tuned mass damper. The working principle of the magneto-rheological tuned mass block is that a plurality of resistance reducing sliders are arranged in the magneto-rheological tuned mass block, and the resistance reducing sliders slide in magneto-rheological fluid to eliminate shock of the super-high-rise buildings caused by earthquakes or strong wind; and the outer portion of the magneto-rheological tuned mass block is connected with the leaded steel lamination damper for reducing impact pressure of the magneto-rheological fluid on the structure. The damper has the advantages of good structural force performance, easy implementation, good stability, good shock absorption effect, good safety and the like. A magneto-rheological system has low power consumption, small size and obvious shock absorption effect, and is beneficial to greatly reducing the cost of the tuned mass dampers for high-rise buildings, super-high-rise buildings and tall structures.

Description

technical field [0001] The invention relates to the technical field of wind resistance and earthquake resistance of high-rise, super high-rise and high-rise structures, in particular to a tuned damper for magnetorheological damping of super high-rise buildings. Background technique [0002] The construction of major engineering structures such as high-rise, super-high-rise, and high-rise structures is in the ascendant in my country, and will play an important role in social and economic development for a long time. As a disaster-prone country in my country, the design of disaster prevention and mitigation such as earthquake resistance and wind resistance of high-rise and super high-rise buildings has always been an important issue that affects the safety performance of buildings. Since the beginning of the new century, high-rise, super high-rise and towering structures have entered a period of rapid development, especially the city's landmark buildings have become a symbol o...

Problems solved by technology

When a suspended TMD is used, the pendulum is generally longer, and a damper needs to be installed, which requires a larger space. When a supported TMD is used, the mass of the TMD is relatively large, and the water tank has a Gravity causes the force component, so that the seismic isolation bearing overturns under the pressure and shear deformation. Since there is no anti-overturning device, there is a possibility of overturning. For high-rise, super high-rise and towering structures, they are gravity-sensitive structures. Attachment mass blocks will be unfavorable to the structural force
