Replaceable segmented yielding metal energy dissipation damper
The invention provides a replaceable segmented yielding metal energy dissipation damper. The replaceable segmented yielding metal energy dissipation damper comprises energy dissipation components, a connecting guide rod and a U-shaped connecting end plate, wherein one end of the connecting guide rod extends into the U-shaped connecting end plate, a plurality of energy dissipation components are detachably fixed between the connecting guide rod and the U-shaped connecting end plate, and the energy dissipation components are located on the two sides of the connecting guide rod respectively; and the energy dissipation components comprise annular energy dissipation components and hole opening energy dissipation components, and the two ends of the hole opening energy dissipation components are fixed in the annular energy dissipation components. The metal damper can meet the requirements of energy dissipation and shock absorption of a building, is convenient to disassemble, can replace part of the components to continue to work efficiently, and can achieve segmented yielding. Firstly, energy dissipation is carried out through shearing plastic deformation of hole opening energy dissipation steel plates, then inner U-shaped steel plates generate plastic deformation, second-stage energy dissipation is carried out, then outer U-shaped steel plates carry out third-stage energy dissipation, and the safety and the shock absorption effect of the metal damper are improved.
一种可更换的分段屈服耗能阻尼器，包括耗能构件、连接导杆和U型连接端板，连接导杆的一端伸入U型连接端板内，连接导杆与U型连接端板之间可拆卸的固定有若干耗能构件，各耗能构件分别位于连接导杆两侧；耗能构件包括环形耗能构件和开孔耗能构件，开孔耗能构件两端固定在环形耗能构件内。本发明的金属阻尼器不仅能满足建筑消能减震的需求，并且拆卸方便，能够更换部分构件以继续高效工作，能够实现分阶段屈服。首先，通过开孔耗能钢板的剪切塑性变形进行耗能，进而，内U型钢板产生塑性变形，进行第二阶段耗能，进而，外U型钢板进行第三阶段耗能，提高了该金属阻尼器的安全性及减震效果。
