Abstract

The invention provides a bidirectional multi-frequency rectangular lattice type tuned liquid damper and relates to a building structure shock controlling device. The bidirectional multi-frequency rectangular lattice type tuned liquid damper is formed by a rectangular-section container, a lattice plate, in-built solution and a fixed part. The damper is simple, practical, convenient to maintain, low in cost, suitable for use in a short term and in a long term, good in self-activation, small in required space, simple to install and convenient to use. The transverse and longitudinal earthquake reactions are controlled by adjusting transverse and longitudinal dimensions, the earthquake reactions under the effects of different formations can be controlled by adjusting the transverse dimension of a lattice, and the fact that a tuned liquid damper designed according to natural vibration frequency of a high-order structure is tall and narrow is avoid. The amount of the dampers is increased correspondingly according to increase of formation orders so as to improve sensitivity of controlling of high-order formation wind vibration and earthquake reactions. When meeting with an earthquake or strong wind, the bidirectional multi-frequency rectangular lattice type tuned liquid damper can reduce power reaction of a building structure and has good protecting effect on the building structure.

Description

technical field

[0001] The invention relates to a building structure vibration control device, in particular to a bidirectional multi-frequency rectangular lattice tuning liquid damper for building structure vibration control. Background technique

[0002] At present, the basic idea of ​​seismic design of "ductile structural system" is generally adopted in my country and other countries in the world. This kind of anti-seismic structure system allows the structure and load-bearing components (columns, beams, nodes, etc.) to be damaged in the earthquake, that is, relying on the damage of the structure and load-bearing components consumes most of the energy, which often leads to serious damage or even collapse of the structure during the earthquake. To a certain extent, it is unreasonable and unsafe. In 1972, Professor J T P Yao, a Chinese-American scholar, proposed the concept of vibration control of civil engineering structures for the first time on the basis of predecessors...

Embodiment Construction

[0013] The present invention will be described in detail below in combination with technical solutions and with reference to the accompanying drawings.

[0014] The two-way multi-frequency rectangular lattice tuned liquid damper proposed by the present invention is as follows: Figure 1~Figure 3 shown.

[0015] The whole device is mainly composed of a rectangular container 6, several lattice panels 7, fixed parts 8, internal solution 10,

[0016] 2 damper containers for controlling the 1st order formation 1, 2 damper containers for controlling the 2nd order formation, 4 damper containers for controlling the 3rd order formation 3, 16 for controlling the 4th order formation The damper container 4 and 32 damper containers 5 for controlling the 5-order formation.

[0017] According to the vibration control requirements, the overall size of the damper and the size of the corresponding formation dampers of each order are determined. Weld the floor with the surrounding maintenance...
