Double-step bending type mild steel damper
The invention discloses a double-step bending type mild steel damper which comprises an upper connecting plate and a lower connecting plate, an X-shaped plate is fixed between the upper connecting plate and the lower connecting plate, a rib plate is further fixed between the end of the upper connecting plate and the end of the lower connecting plate, and the rib plate is perpendicularly welded to the upper connecting plate and the lower connecting plate. The plane where the rib plates are located is perpendicular to the plane where the X-shaped plates are located, the X-shaped plates are used for achieving longitudinal damping, and the rib plates are used for achieving transverse damping. According to the double-step bending type mild steel damper, in the elastic stage of the mild steel damper, the X-shaped plates and the rib plates do not yield to dissipate energy and only provide additional rigidity for the structure, and the rib plates are arranged so that interlayer lateral displacement of a frame can be reduced easily; in the plastic stage of the mild steel damper, the X-shaped plates and the rib plates start to conduct yield energy dissipation work, additional rigidity and additional damping are provided for the structure, and the seismic response of the structure can be effectively reduced; through two-stage yield, the problem of energy consumption and shock absorption of two frequency bands is solved.
本发明公开了一种双阶弯曲型软钢阻尼器，包括上连接板和下连接板，所述上连接板和下连接板之间固定有X形板，上连接板和下连接板的端部之间还固定有肋板，肋板与上连接板以及下连接板垂直焊接，肋板所在平面与X形板所在平面相垂直，X形板用于实现纵向的减震，而肋板则用于实现横向的减震。该双阶弯曲型软钢阻尼器，在软钢阻尼器的弹性阶段，X形板和肋板未进入屈服耗能，只为结构提供附加刚度，肋板的设置有利于减小框架的层间侧移；在软钢阻尼器塑性阶段，X形板和肋板开始进入屈服耗能工作，为结构提供附加刚度和附加阻尼，能够有效的减小结构的地震响应；通过两阶段的屈服，解决两个频段的耗能减震问题。
