Prefabricated assembled hollow pier combining internal and external energy dissipation steel plates
The invention discloses an internal and external energy dissipation steel plate combined prefabricated assembled hollow pier which comprises a foundation, a bottom section, a middle section and a top section, the bottom section, the middle section and the top section are mounted above the foundation, and the bottom section is connected with the foundation through an L-shaped energy dissipation steel plate and an internal buckling type energy dissipation steel plate. The bottom section, the middle section and the top section are connected through the inner buckle type energy dissipation steel plates, the L-shaped energy dissipation steel plates are arranged on the outer side of the bottom of the bottom section, and the inner buckle type energy dissipation steel plates are arranged on the inner sides of the bottoms of the bottom section, the middle section and the top section. The L-shaped energy dissipation steel plate convenient to replace is installed on the inner side of the bottom section, and the energy dissipation capacity of the pier at the bottom section is enhanced; and meanwhile, an inner buckle type energy dissipation steel plate is arranged at the joint of each section of the bridge pier to limit plastic deformation of the concrete bridge pier, and the upper section participates in energy dissipation of the bridge pier, so that each section of the bridge pier reasonably distributes the action of an earthquake on the bridge pier in the earthquake process, multi-stage energy dissipation is realized, and the energy dissipation capacity in the earthquake process is enhanced.
本发明公开了一种内外耗能钢板结合的预制拼装空心桥墩，包括基础、以及安装在基础上方的底部节段、中部节段和顶部节段，底部节段通过L型耗能钢板、内扣型耗能钢板与基础相连接，底部节段、中部节段和顶部节段之间通过内扣型耗能钢板相连接，L型耗能钢板设置在底部节段底部外侧，内扣型耗能钢板设置在底部节段、中部节段与顶部节段底部内侧。本发明在底部节段内侧安装便于更换的L型耗能钢板，增强底部节段处桥墩的耗能能力；同时在各节段桥墩接缝处配置内扣型耗能钢板，限制混凝土桥墩的塑性变形，让上部节段参与到桥墩耗能当中，从而使得桥墩各节段合理分配地震过程中地震对桥墩的作用，实现多级耗能，增强在地震过程中的耗能能力。
