Prefabricated pier plastic hinge structure capable of being quickly replaced after earthquake
A prefabricated pier plastic hinge structure capable of being quickly replaced after an earthquake relates to the technical field of bridge engineering and comprises a pier and a bearing platform arranged at the bottom end of the pier, the pier comprises a non-plastic hinge area located on the upper portion and a plastic hinge area located on the lower portion and composed of a plastic hinge structure, the plastic hinge structure comprises a prefabricated stiff framework connected between the lower end of the non-plastic hinge area and the upper end of the bearing platform, an assembly type prefabricated energy dissipation protection layer arranged on the periphery of the prefabricated stiff framework, and a self-resetting energy dissipation device which penetrates through the prefabricated energy dissipation protection layer in the longitudinal direction and is fixedly connected with a steel plate A and a steel plate B of the prefabricated stiff framework. The bridge pier can still keep the using function after an earthquake or can recover the using function through simple repairing, and the repairing process can be rapidly completed by replacing the prefabricated parts.
一种震后可快速更换的预制桥墩塑性铰结构，涉及桥梁工程技术领域，包括桥墩、以及设于桥墩底端的承台，所述的桥墩包括位于上部的非塑性铰区和位于下部且由塑性铰结构构成的塑性铰区，所述的塑性铰结构包括连接于非塑性铰区的下端与承台上端之间的预制劲性骨架、设于预制劲性骨架外周的拼装式预制耗能保护层、以及沿纵向贯穿预制耗能保护层并与预制劲性骨架的钢板A和钢板B固定连接的自复位耗能装置。本发明可使桥墩在震后仍能保持使用功能或经简单修复即可恢复使用功能，且修复过程可通过更换预制构件快速完成。
