Novel self-resetting bridge pier with hollow hexagonal steel tube energy dissipation system and application of novel self-resetting bridge pier
The invention discloses a novel self-resetting pier with a hollow hexagonal steel tube energy dissipation system and application of the novel self-resetting pier. Belongs to the technical field of bridge seismic resistance and seismic mitigation and isolation. The pier comprises a pier body, an anchoring plate, a prestressed steel beam, an energy dissipation system, angle steel, a bearing platform and the like, the two sides of the pier bottom of the pier body are connected with angle steel through a cast-in-place method and shear keys, and the side face of the pier body is anchored to a bearing platform through an anchoring plate and a prestressed steel beam. Main components of the energy dissipation system are composed of hollow hexagonal steel pipes, bolts, built-in springs, base plates and nuts, and the energy dissipation system is fixedly installed on the two sides of the bottom of the pier body and connected with angle steel. Potential inelastic deformation can be borne, major components of the structure are prevented from being seriously damaged, so that enough energy dissipation capacity is provided for a structural system while the strength and rigidity of the system are shared, and the pier structure has a self-resetting function due to the prestressed steel beams and the hollow hexagonal steel pipes; the energy consumption system has the advantages of being easy to install, replaceable, convenient to maintain and monitor and diversified in energy consumption component.
本发明公开了一种带空心六角钢管耗能系统的新型自复位桥墩及其应用。属于桥梁抗震及减隔震技术领域。由墩身、锚定板、预应力钢束、耗能系统、角钢和承台等组成；所述墩身在墩底两侧通过现浇方法和剪力键与角钢连接，在墩身侧面通过锚定板和预应力钢束与承台锚固；所述耗能系统的主要部件由空心六角钢管、螺栓、内置弹簧、垫板和螺母组成，安装固定在墩身底部两侧与角钢连接。它可以承受潜在的非弹性变形，避免结构的主要构件发生严重损坏，从而在共享系统强度和刚度的同时为结构系统提供足够的能量耗散能力，预应力钢束和空心六角钢管使桥墩结构具有自复位的功能，耗能系统有着易安装、可更换、便于养护监测和耗能构件多样化的特点。
