Embodiment Construction

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention.

[0025] An annular liquid damper disclosed by the invention is mainly used for shock absorption of a towering steel chimney structure, and solves damage to the steel chimney structure caused by pulse vibrations generated by horizontal and vertical winds. Of course, in addition to being applied to high-rise steel chimneys, other main structures that require shock absorption can also be applied, and the present invention is not limited. The structure and working principle of the annular liquid damper of the present invention will be specifically introduced below by taking the application to steel chimney structures as an example. .

[0026] Such as figure 2 As shown, a kind of annular liquid damper disclosed by the present invention includes at least two layers of annular liquid damper...

Abstract

The invention discloses an annular liquid damper mainly used for damping a steel chimney. The annular liquid damper comprises at least two layers of annular liquid damper bodies vertically connected in series, each annular liquid damper body is composed of one or more water tanks, and each water tank comprises a tank body, a horizontal damping net and a vertical damping net, wherein the horizontal damping net is fixed to the inner side wall of the tank body, one end of the vertical damping net is fixed to the bottom of the tank body, the other end of the vertical damping net is fixed to the horizontal damping net, and tuning liquid is contained in the water tank. As the horizontal damping net and the vertical damping net are added into each water tank, the damping ratio of the TLD (tuned liquid damper) is increased, and the TLD meets the optimal damping ratio requirement needed by the steel chimney; meanwhile, two or more layers of water tanks vertically connected in series are adopted according to structural stress calculation, and therefore the annular liquid damper can be used for damping a steel chimney with the diameter of 25 m or more.

Description

technical field [0001] The invention relates to a tuned liquid damper, in particular to an annular liquid damper which can obtain the best damping effect, has low manufacturing cost and is mainly used for chimney damping. Background technique [0002] In recent years, with the continuous and in-depth research on the structure's earthquake resistance and disaster reduction, the new type of damper has gradually attracted people's attention. Among them, the tuned liquid damper (Tuned Liquid Damper, TLD for short) system is composed of the water tank and the liquid in the water tank. When the main structure is excited to vibrate, it will cause the liquid in the TLD tank to slosh and form waves on the surface of the liquid. The sloshing liquid and waves will generate a dynamic pressure difference on the TLD tank wall. At the same time, the liquid movement will also cause inertial force, dynamic pressure difference and The resultant force of the liquid inertial force is opposite ...
