Abstract

The invention provides a universal swing track supporting turned mass damper. The damper comprises a support, a hemispherical mass block, a cable-stayed spring and a damper body; the support is shaped like a cylinder, the upper portion of the support is provided with a circular-arc concave surface which is provided with a heavy universal sphere, the bottom of the hemispherical mass block is arranged in the circular-arc concave surface, and the periphery of the upper portion of the hemispherical mass block is connected with the support through the cable-strayed spring and the damper body. A high-damping rubber buffer layer is arranged on the circular-arc concave surface of the support, and the heavy universal sphere is fixed on the high-damping rubber buffer layer. According to the universal swing track supporting turned mass damper, wind vibration in different directions and earthquake structure responses can be controlled, the hemispherical mass block can universally swing under the action of wind vibration and earthquakes, and when the hemispherical mass block swings, the cable-stayed spring and the viscous liquid damper can move to dissipate energy simultaneously.

Description

technical field [0001] The invention relates to a tuned mass damper assembled on the upper part of a building under the action of a heavy-duty universal ball track support system, belonging to the technical field of vibration control of civil structures, in particular to a universal damper for wind and earthquake resistance of structures. Sport's tuned mass dampers. Background technique [0002] With the development of wind and earthquake resistance design theory of civil engineering structures, traditional design methods are difficult to meet the needs of earthquake and wind resistance design. Vibration control theory, technology and application results, research and application of civil engineering structure vibration control technology. With the rapid development and practice of structural vibration control technology, the Tuned Mass Damper (TMD) system as a traditional structural passive vibration reduction system has become a research hotspot in civil engineering and h...
