Abstract

The invention relates to an energy-dissipation connecting beam device used for a building engineering structure. The device comprises a left anti-seismic connecting beam, a right anti-seismic connecting beam, connecting end devices and a liquid inertial mass damper. The upper and lower ends of the liquid inertial mass damper and the anti-seismic wall connecting beams of a building structure are connected through the connection end devices correspondingly. The liquid inertial mass damper is vertically arranged between the left and right anti-seismic wall connecting beams. The energy-dissipation connecting beam device is composed of the anti-seismic wall connecting beam units, the liquid inertial mass damper and the mounting connecting devices, two joint mass units with the mass amplification effect of the liquid inertial mass damper are fully utilized to absorb energy, and a damper eddy current unit is utilized to dissipate energy. Through mounting units arranged on the liquid inertial mass damper and the left and right anti-seismic wall connecting beams, mounting and adjustment are convenient. According to the energy-dissipation connecting beam device, arrangement is convenient and flexible, the vibration energy can be effectively absorbed and dissipated, the energy-dissipation connecting beam device is especially suitable for bending type deformation structures, the additionally-arranged damper is small in actual mounting mass, and good application and popularization value is achieved.

Description

technical field [0001] The invention relates to an energy-dissipating connecting beam equipped with a liquid inertial mass damper, and belongs to the technical field of energy-dissipating and shock-absorbing civil engineering structures. Background technique [0002] Seismic wall structure is an effective anti-lateral force structural system, which is gradually widely used in modern high-rise or super high-rise building structures. Under the action of moderate or large earthquakes, the energy dissipation of the combined seismic wall is mainly realized by the plastic hinges of the connecting beams and the foot of the wall, and its energy dissipation capacity also directly affects the safety of the seismic wall. [0003] Energy dissipation and vibration reduction technology is to add energy dissipation and vibration reduction devices to the structure. The additional vibration reduction devices and the structure itself bear the effects of earthquakes and wind vibrations. The dy...
