Pure bending moment yield damper device
The invention discloses a pure bending moment yield damper device. The pure bending moment yield damper device comprises supporting frame connectors, energy dissipation plates, supporting plates, guide grooves, shear keys, rolling supports and lateral constraint masonry. According to the pure bending moment yield damper device, the pressure distribution is uniform, the energy dissipation plates atthe extension part generate pure bending moment, the ductility is high, and it is effectively avoided that when the extension part is used in a welding fixed connection mode, axial force is likely tobe generated, local plastic hinges are caused, and the ductility of the welding position is reduced; the energy consumption performance of the device is improved, the energy absorption and shock absorption performance is high, and the energy consumption effect is good; and the manufacturing cost is low, the operation and later maintenance cost is low, the maintenance and replacement cost after serious earthquake disasters is low, and the applicability is good.
本发明公开了一种纯弯矩屈服阻尼器装置，包括支撑架连接口、耗能板、托板、导向槽、剪力键、滚动支座、侧向约束砌体；本发明的纯弯矩屈服阻尼器装置，压力分布均匀，延展部位耗能板产生纯弯矩，延展度高，有效避免了延展部位采用焊接的固定连接方式使用时易产生轴向力，造成局部塑性铰、焊接处的延展度降低；提高了装置的耗能性能，吸能减震性能高，耗能效果佳；制作成本低，运行及后期维护费低，严重地震灾害后维修更换费用低，应用性好。
