Description

TECHNICAL FIELD

[0001] The utility model relates to the field of building anti-seismic technology, especially a buckling restrained brace structure for high piers with tie beams and double columns. BACKGROUND

[0002] The high pier with tie beams and double columns is a common pier structure form in bridge engineering, which mainly comprises two columns and a tie beam connecting the two columns, and the height of the pier is relatively high. This structure form is suitable for bridge construction across valleys, rivers and other places requiring large bridge clearance or under special geological conditions such as soft soil foundation. The buckling restrained brace, also known as the buckling restrained brace, converts seismic energy into heat and other forms through its deformation, thereby reducing the damage of seismic energy to the main structure of the high pier with tie beams and double columns.

[0003] The existing buckling restrained brace structure is usually connected with the building structure by welding. Although the welding connection can provide firm connection strength, once the welding is completed, it is not convenient to disassemble the buckling restrained brace when it is damaged or its performance is degraded after long-term use, thereby reducing the use effect. In addition, the high pier with tie beams and double columns is subjected to various loads during use, and the directions and modes of action of different loads are different, so that the existing buckling restrained brace structure cannot well adapt to these different load conditions, thereby reducing the supporting effect.
