Abstract
Description
Technical Field
[0001] The utility model relates to the field of bridge construction, in particular to a multi-directional displacement tower-beam damping connection device. Background Art
[0002] In order to improve the seismic performance of long-span bridges, dampers are usually installed between the piers and the main beams. The existing dampers, as described in patent number "CN115323925A", absorb the vibration energy of the bridge by axial expansion and contraction of the damper after connecting the piers and the main beams. However, when the bridge is designed as a flexible system, the main beam of the bridge may produce a large lateral deformation in a vibration environment such as an earthquake. At this time, in order to absorb the vibration energy, when the damper expands and contracts, its two ends will move with the main beam and the piers, causing the damper's oil cylinder to bend and deform, resulting in a cylinder jam. The damper is very easy to damage and has low durability, so it needs to be solved urgently. Utility Model Content
