Description

technical field [0001] The invention belongs to the field of vibration control of building structures, in particular to an assembled energy-dissipating wall device for vibration reduction, which can be used to reduce wind vibration and earthquake responses of building structures. Background technique [0002] In order to reduce the wind vibration and earthquake response of the building structure, energy-dissipating components in the form of walls are usually installed in the building structure to achieve a better energy-dissipating effect. Common damping materials for energy-dissipating wall devices include mild steel, viscoelastic materials, and viscous damping materials. However, since these damping materials have only a single energy dissipation mechanism, their corresponding energy dissipation wall devices will cause corresponding performance defects. For example, due to the large temperature-frequency correlation of viscoelastic materials, the damping force provided by...

However, since these damping materials only have a single energy dissipation mechanism, their corresponding energy dissipation wall devices will cause corresponding performance defects

For example, due to the large temperature-frequency correlation of viscoelastic materials, the damping force provided by viscoelastic energy-dissipating walls is difficult to meet the requirements of practical engineering.
