InactiveCN102304892AStable energy consumptionEnsure safetyBridge structural detailsBridge erection/assemblyBridge engineeringExternal energy
The invention discloses an external energy-consumption self-resetting bridge pier stud structure system and a realization method thereof, belonging to the field of bridgework. The structure system mainly comprises a bridge pier stud, a bridge abutment, an unbonded prestressed reinforcement, an external energy consumption device, a pier embedded part and a bridge abutment embedded part, wherein the bridge pier stud and the bridge abutment are connected by the unbonded prestressed reinforcement and the external energy consumption device, so that residual deformation can be effectively reduced, and energy consumption can be guaranteed. The external energy-consumption self-resetting bridge pier stud structure system is flexible in design and has specific structure stress. The unbonded prestressed reinforcement on the axis position of the pier stud can be used for generating self-resetting restoring force. The problem that the traditional bridge pier has larger residual deformation and cannot continuously serve after the earthquake loading action is solved. The bridge pier has enough strength and rigidity. The external energy-consumption self-resetting bridge pier stud structure system is realized in a cast-in-situ or prefabricating mode and is easy to construct and is a novel pier stud structure system which is advanced and practical and can realize quick replacement and repair after the earthquake..
