Problems solved by technology

In the process of design and installation, the scheme of suspending a mass block is often adopted, but if the mass mass is too large, the foundation load will be increased and the cost will be increased; if the mass mass is too small, the vibration damping effect will be poor

Abstract

The invention discloses a towering vibration reduction chimney with an inerter device. The towering vibration reduction chimney comprises a chimney outer cylinder and a chimney inner cylinder, wherein the chimney outer cylinder and the chimney inner cylinder are connected through a bearing rod or a bearing spring, and the inerter device is connected between the chimney outer cylinder and the chimney inner cylinder. According to the towering vibration reduction chimney, the chimney inner cylinder is used as an additional mass body and forms an inerter damper with the inerter device, the vibration resistance of the towering chimney under the action of wind-induced vibration and earthquakes is improved, the mass amplification effect of an inerter element is used, and the structural response and displacement response of the chimney are further reduced by applying the resonance principle. The towering vibration reduction chimney has the characteristics of simple design, simple structure, convenient installation and cost saving.

Description

technical field [0001] The invention relates to the technical field of vibration damping of towering chimneys, in particular to a towering vibration damping chimney with an inertial capacity device. Background technique [0002] With the continuous development of the civil engineering industry, the wind and vibration resistance technology of civil buildings has become more and more mature, while the seismic and wind resistance performance of common chimney structures in industry still needs to be optimized. Tall chimneys are mainly affected by wind loads and seismic loads, and traditional tuned mass dampers are often used to reduce vibration. [0003] The traditional tuned mass damper is installed on the top of the chimney structure, and uses the resonance principle to transfer the vibration energy absorption of the main structure to the control device and consume it, thereby reducing the wind vibration and seismic response of the chimney structure. In the process of design...
