Double-column type swinging shock-insulation bridge pier structure system
The invention provides a double-column type swinging shock-insulation bridge pier structure system and belongs to the field of bridge engineering. The structure system is mainly composed of an upper structure, a reinforced concrete bridge pier section and a steel pipe concrete bridge pier section, a bearing platform, a steel pipe concrete bolt pin, a non-binding pre-stress steel bar and the like. The steel pipe concrete bridge pier section is connected with the upper structure through the non-binding pre-stress steel bar; and with the help of an external energy consumption device and a metal annular object, the shock-insulation effect and the self-resetting capability of a bridge structure can be effectively provided. The structure system designed by the invention has a definite stress mechanism; under the condition of ensuring that the structure system has enough intensity and rigidity, the earthquake effect borne by the structure is reduced, and the effective energy consumption capability and self-resetting capability can be provided; and the problems of a traditional double-column type bridge pier structure system that a support is replaced in a life period and the system is seriously damaged and has large residual deformation after the earthquake effect can be solved.
