Double-order yield metal bending damper
The invention discloses a double-step yield metal bending damper which comprises an upper-layer steel plate, a lower-layer steel plate, a connecting plate with a sliding groove, an X-shaped steel plate, a triangular steel plate, a sliding shaft, a connecting screw and a screw gasket. The tops of a plurality of triangular steel plates are arranged in the upper-layer steel plate slots and are welded with the upper-layer steel plate; a groove is formed in the lower portion of the triangular steel plate in advance, a sliding shaft is arranged in the groove, the two sides of the sliding shaft are arranged in two connecting plates respectively, and the two connecting plates are welded to the lower-layer steel plate; under the action of a small earthquake, the up-down relative displacement of the damper is small, the two X-shaped steel plates on the outer side are firstly bent to enter a yield state to dissipate energy, and the triangular steel plate in the middle is in an elastic state under the action of the small earthquake and does not enter the yield stage; when the damper is subjected to a large earthquake, the relative displacement of the upper and lower steel plates is increased, the triangular steel plates also enter a flexural yielding state, and the two steel plates consume energy together. By controlling the relevant parameters of the two steel plates, the effect of staged energy consumption under the action of large earthquakes and small earthquakes can be achieved.
本发明公开了一种双阶屈服金属弯曲阻尼器，包括上层钢板、下层钢板、带滑槽连接板、X型钢板、三角形钢板、滑动轴、连接螺钉、螺钉垫片。多块三角形钢板顶部置入上层钢板开槽当中，并与上层钢板焊接连接；三角形钢板下部预先开槽，并置入滑动轴，滑动轴两侧分别置入两块连接板中，两块连接板焊接在下层钢板上；在小震作用下阻尼器上下相对位移小，外侧两块X型钢板首先受弯进入屈服状态耗能，而中间三角形钢板在小震作用下处于弹性状态，未进入屈服阶段；在阻尼器受到大震作用时，上下两层钢板相对位移增大，三角形钢板也进入受弯屈服状态，两种钢板共同耗能。通过控制两种钢板的相关参数，本发明可起到在大震小震分别作用下分阶耗能的效果。
