Metal composite energy dissipater with double-order yield points for shock insulation layer
The invention provides a metal composite energy dissipater with double-order yield points for a shock insulation layer. The metal composite energy dissipater comprises a first yield energy dissipation section and a second yield energy dissipation section. The first yield energy dissipation section is formed by orthogonally arranging four groups of spiral steel bar energy dissipation units and is used for absorbing earthquake energy input in two directions; and the second yield energy dissipation section is made of a variable-cross-section yield energy dissipation lead pipe, and end plates are arranged at the upper end and the lower end of the second yield energy dissipation section to provide end restraint. The metal composite energy dissipater has the deformation capacity matched with large-earthquake displacement of the shock insulation layer, and under the action of a rare earthquake and under the condition that the shock insulation layer has larger displacement, the normal energy dissipation and shock absorption working state can still be kept; and meanwhile, the metal composite energy dissipater has the characteristic of double-order yield energy dissipation, the output of the metal energy dissipater can be increased in stages along with the increase of the earthquake action, a hysteretic energy dissipation curve of a damper is full under different earthquake magnitudes, and it is guaranteed that the metal composite energy dissipater has the excellent energy dissipation and shock absorption effect under the different earthquake magnitudes.
本发明提供了一种用于隔震层的具有双阶屈服点的金属复合消能器，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螺旋形钢棒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变截面屈服耗能铅管制成，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，在罕遇地震作用下，隔震层发生较大位移的情况下，本发明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，在不同的震级下，该阻尼器的滞回耗能曲线饱满，保证该金属复合消能器在不同震级下均具有优良的耗能减震效果。
