Bidirectional shear damper
The bidirectional shear damper comprises a bottom plate, a top plate and steel bars, the bottom plate and the top plate are vertically arranged in parallel, steel bar hole positions are formed in the opposite positions of the bottom plate and the top plate, and the two ends of each steel bar are arranged in the steel bar hole positions in the bottom plate and the steel bar hole positions in the top plate respectively and fixedly welded to the bottom plate and the top plate. According to the scheme provided by the embodiment of the invention, the steel bars bear the bending and shearing effects and serve as metal yield type dampers to consume earthquake energy, the steel bars work independently, stress is uniform, shearing in the double-orthogonal direction or the oblique direction can be borne, certain pressure and torsion can be borne, external buckling of the shearing face can be avoided, and the earthquake energy is saved. The ductile energy consumption effect of the material is favorably exerted; the structure is simple, processing and manufacturing are convenient, and cost is low.
本发明实施例提供了一种双向剪切阻尼器，包括上下平行设置的底板和顶板，以及钢棒，底板和顶板上相对位置处开设有钢棒孔位，钢棒的两端分别置于底板和顶板上的钢棒孔位内，并与底板和顶板焊接固定。本发明实施例提供的方案，通过钢棒承受弯剪作用并作为金属屈服型阻尼器消耗地震能量，每根钢棒之间相对独立工作，受力均匀，可承受双正交方向或斜方向的剪切，并可承受一定的压力和扭转，可避免剪切面外屈曲，有利于发挥材料的延性耗能作用；并且结构简单，加工制作方便，成本低廉。
