Two-way two-step yielding metal energy dissipater suitable for shock insulation layer
The invention provides a two-way two-step yielding metal energy dissipater suitable for a shock insulation layer. The two-way two-step yielding metal energy dissipater comprises a first yielding energy dissipation section and a second yielding energy dissipation section, wherein, the first yield energy dissipation section is formed by orthogonally arranging four sets of U-shaped energy dissipation units and is used for absorbing earthquake energy input in two directions; and the second yield energy dissipation section is formed by orthogonally arranging two sets of shear yield energy dissipation steel plates, and end plates are arranged at the upper end and the lower end of the second yield energy dissipation section to provide end constraint. The metal energy dissipater has the deformation capacity matched with large-earthquake displacement of the shock insulation layer, and the normal energy dissipation and shock absorption working state can still be kept under the large-earthquake displacement of the shock insulation layer; and meanwhile, the metal energy dissipater has the characteristic of two-step yielding energy dissipation, the output of the metal energy dissipater can be increased in stages along with the increase of the earthquake action, and it is guaranteed that the metal energy dissipater has the excellent energy dissipation and shock absorption effect under different earthquake magnitudes.
本发明提供了一种适用于隔震层的双向双阶屈服的金属消能器，包括：第一屈服耗能段和第二屈服耗能段；所述第一屈服耗能段由四组U形耗能单元正交布置而成，用于吸收两个方向输入的地震能量；所述第二屈服耗能段由两组剪切屈服耗能钢板正交布置而成，并在上下两端设置端板提供端部约束。本发明具有匹配隔震层大震位移的变形能力，在隔震层较大位移下仍能保持正常的耗能减震工作状态；同时具有双阶屈服耗能的特点，随着地震作用的增加，该金属消能器的出力可分阶段提升，保证该金属消能器在不同震级下均具有优良的耗能减震效果。
