Abstract

The invention relates to an inerter-based particle damper, comprising fixing plate (3) fixed on a ground, and an inerter unit and a particle damping unit slidably arranged on the bottom; the inerter unit is connected with the particle damping unit through connection spring (7); the fixing plate (3) is connected with the inerter unit through gear unit (2) and drives the inerter unit to move. Compared with the prior art, the inerter-based particle damper with various energy-dissipating aseismic measures has good energy-dissipating capacity and applicability.

Description

technical field [0001] The invention relates to the field of vibration control of civil engineering structures, in particular to a particle damper utilizing inertial capacity. Background technique [0002] Strong earthquakes and hurricanes have been threatening human existence and bringing disasters to people. With the acceleration of economic development and urbanization, civil engineering structures are developing towards higher heights, larger spans, and more complex structures. As a result, once strong earthquakes and hurricanes come, it may bring more serious problems. socioeconomic losses. Therefore, to minimize the losses caused by earthquake disasters and wind disasters is an important problem that human beings must solve. In order to ensure the safety of the engineering structure and the coordination with the building, the environment and the use requirements, the structural vibration control technology, as a safe, economical and effective measure, has become one ...
