Lattice type swinging high pier
The invention relates to a lattice type swinging high pier which is characterized in that four pier columns are connected through an inter-column truss connecting system, under normal use and small earthquake action, the inter-column truss connecting system is in an elastic state, the four pier columns are connected into a whole and cooperatively work, and lateral rigidity for resisting horizontal force is provided for the lattice type swinging high pier; the comfort of railway driving is ensured, and partial structural functions are undertaken; under the action of a strong earthquake, graded energy consumption can be formed, damage to pier columns is reduced through yield energy consumption of a truss coupling system between the columns, and damage to a high-order vibration mode area in the pier is reduced; the self-resetting function is guaranteed through the self-weight of a whole formed by the four pier columns and the inter-column truss connecting system, under normal use and the action of small earthquakes, lifting and swinging are avoided, under the action of strong earthquakes, the pier body formed by the four pier columns above the pile foundation and the inter-column truss connecting system insulates earthquakes through swinging so as to reduce the earthquake response of the pier bottom, and the safety of the pier is improved. The device has good shock insulation and self-resetting effects, and can effectively reduce the damage to the pier bottom.
本发明涉及一种格构式摇摆高墩，采用四个墩柱之间通过柱间桁架联结系连接，在正常使用及小震作用下，柱间桁架联结系处于弹性状态，将四个墩柱连成一个整体，协同工作，并为格构式摇摆高墩提供抵抗水平力的侧向刚度，保证铁路行车的舒适，承担了部分结构功能；在强震作用下，能够形成分级耗能，利用柱间桁架联结系屈服耗能来减小墩柱损伤，减小墩中高阶振型区的损伤；利用四个墩柱和柱间桁架联结系形成的整体的自重保证自复位功能，在正常使用及小震作用下，不提离摇摆，在强震作用下，桩基础以上四个墩柱和柱间桁架联结系形成的桥墩主体通过摇摆隔震，以减小墩底地震反应，其具有良好的隔震及自复位效果，能有效降低墩底的损伤。
