Embodiment

[0014] Example: A device for arranging a frequency-modulated mass damper away from the point of vibration, such as Figure 1-Figure 2 As shown, it includes lifting lugs, a first steel wire rope, a concentric pulley block, a second steel wire rope, a horizontal frequency-modulated mass damper, a tension spring, and a linear guide rail. The concentric pulley block is suspended and fixed on the ground, and the concentric pulley block includes a central shaft and Rotate the first pulley and the second pulley arranged on the central shaft, the first pulley and the second pulley are concentric and fixed together and cannot rotate with each other, that is, the first pulley and the second pulley rotate at the same time and have the same angular velocity , the lifting lug is connected to the structural vibration point, one end of the first steel wire rope is connected to the lifting lug, the other end is wound on the first pulley of the concentric pulley block, one end of the second ste...

Abstract

The invention relates to the technical field of building damping, and discloses a device for arranging a frequency modulation mass damper away from a vibration point. The device comprises a lifting lug, a first steel wire rope, a concentric pulley block, a second steel wire rope, the horizontal frequency modulation mass damper, a tension spring and a linear guide rail, wherein the concentric pulley block is fixed on the ground in a suspended mode, the concentric pulley block comprises a central shaft, a first pulley and a second pulley, the first pulley and the second pulley are rotationally arranged on the central shaft, the first steel wire rope is connected with the lifting lug and the concentric pulley block, and the second steel wire rope is connected with the concentric pulley blockand the horizontal frequency modulation mass damper. According to the device, vibration in any direction of the upper part of the structure can be transmitted to the horizontal frequency modulation mass damper installed at the bottom of the structure, so that early-stage installation and later-stage maintenance of the horizontal frequency modulation mass damper are facilitated.

Description

technical field [0001] The invention relates to the technical field of building shock absorption, in particular to a device for arranging a frequency-modulated mass damper away from a vibration point. Background technique [0002] In order to control the horizontal or vertical vibration of the building structure under the excitation of external loads, a frequency-modulated mass damper is often arranged at the structural vibration point. For example, a high-rise structure will arrange a horizontal frequency-modulated mass damper on the top of the structure, and a long-span structure will arrange a vertical frequency-modulated mass damper at the maximum vibration acceleration of the floor. These two kinds of frequency-modulated mass dampers need to be arranged near the vibration point, that is, both frequency-modulated mass dampers need to be arranged in the superstructure. Such an arrangement will increase the difficulty of early installation and later maintenance costs of t...
