Description

Technical Field

[0001] This utility model relates to the field of bridge bearing technology, and in particular to a multi-dimensional damping vibration control device for bridges. Background Technology

[0002] Bridge structures, as vital infrastructure, are characterized by their strong public nature, large construction investments, and difficulties in operation and maintenance. The superstructure faces the dual threats of structural vibration and seismic forces, necessitating improvements in vibration reduction and seismic resistance, making related technologies urgently needed. Therefore, enhancing the seismic isolation and vibration reduction performance of bridges is a fundamental measure to reduce earthquake and vibration losses.

[0003] Currently, most bridge seismic isolation bearings on the market primarily isolate horizontal earthquakes, but their effect on reducing vertical seismic forces or vibrations in the superstructure is not significant. Furthermore, buildings typically control either earthquakes or vibrations from rail transit, rarely controlling both simultaneously. Seismic isolation and vibration damping products on the market are usually two separate products. Therefore, there is an urgent need for a multi-dimensional damping and vibration control device that can reduce both horizontal seismic forces on the superstructure and the impact of vertical earthquakes and vibrations.
