Energy dissipation rod and modular multi-stage adjustable shear damper
The invention relates to an energy dissipation rod and a modular multistage adjustable shear damper, the energy dissipation rod comprises a constraint sleeve, two energy dissipation cores, a connecting sleeve and a constraint spring, the two energy dissipation cores penetrate through the constraint sleeve, and each energy dissipation core comprises a connecting section, a yield section and an elastic section which are sequentially connected with one another in the axis direction; the connecting section and the yield section are located in the restraining sleeve, and part of the elastic section is located in the restraining sleeve. The elastic section comprises external thread sections, and the external thread sections are arranged at the two ends of the elastic section; the two ends of the connecting sleeve are fixedly connected to the connecting sections respectively; the two restraining springs are arranged on the yield sections in a sleeving mode correspondingly. Compared with a grouting type energy dissipation rod in the prior art, the energy dissipation rod provided by the invention is simple in structure and easy to assemble; compared with an all-steel energy dissipation bar in the prior art, the constraint spring provides sufficient constraint for the yield section of the energy dissipation core, so that the yield section sufficiently deforms to dissipate energy, and the stability, buckling energy dissipation capacity and bearing capacity of the energy dissipation core are improved.
本发明涉及一种耗能杆及模块化多级可调控剪切阻尼器，其中，耗能杆包括约束套筒、耗能内核、连接套筒和约束弹簧，耗能内核贯穿于约束套筒，具有2个且沿轴线方向包括依次相互连接地连接段、屈服段和弹性段，连接段和屈服段位于约束套筒内，部分弹性段位于约束套筒内；弹性段包括外螺纹段，外螺纹段设于弹性段的两端；连接套筒固接于约束套筒且其两端分别固接于连接段；约束弹簧具有2个且分别套设于屈服段。本发明提供的耗能杆，与现有技术中的灌浆型耗能杆相比，结构简单，易于装配；与现有技术中全钢型耗能杠相比，约束弹簧为耗能内核的屈服段提供充分地约束，使得屈服段充分变形耗能，提升耗能内核的稳定性、屈曲耗能能力以及承载力。
