The invention discloses a metal damper capable of limiting vertical deformation, and belongs to the field of structural damping. The main body comprises trapezoidal steel plates, connecting plates, limiting blocks, load-bearing bearings, H-shaped steel plates and metal energy dissipation pieces. The H-shaped steel plates and the connecting plates are in contact through the fixed load-bearing bearings to roll, so that when vertical displacement exists between beams, it is guaranteed that the metal energy dissipation pieces in the middle are only subjected to horizontal in-plane shearing, and vertical tension and compression deformation is avoided. The metal material in the middle is an energy dissipation body and is subjected to shear deformation. Under strong earthquakes and strong aftershocks, force transmission is reliable, the low-cycle fatigue performance is good, large deformation can be generated under the earthquake effect, and therefore larger energy is dissipated. And disassembly is convenient after strong shock, and rapid repairing of the main body structure is facilitated.
本发明公开了一种限制竖向变形的金属阻尼器，属于结构减震领域。主体包括梯形钢板、连接板、限位块、承重轴承、H型钢板和金属耗能片。通过固定的承重轴承接触H型钢板和连接板发生滚动，以适用于梁间有上下位移时，保证了中间的金属耗能片只发生水平向的面内剪切，而不发生竖向拉压变形。中间的金属材料为耗能主体，发生剪切变形。本发明在强震以及强余震下传力可靠，低周疲劳性能好，在地震作用下可发生较大变形，从而耗散更大的能量。并且强震后拆卸方便，便于实现主体结构快速修复。
