Deformation-controlled knee brace of disc spring parallel metal energy dissipater
The invention discloses a deformation controlled knee brace of a disc spring parallel metal energy dissipater. The deformation controlled knee brace comprises an inner metal rod, an outer metal pipe, a standby pull rod-disc spring system and an external metal energy dissipater. The inner metal rod is inserted into the outer metal pipe and connected through the standby pull rod-disc spring system inside the outer metal pipe, and the outer surface of the inner metal rod is connected through the external metal energy dissipater. The standby pull rod-disc spring system is fixedly connected with the outer metal pipe and is slidably connected with the inner metal rod. The standby pull rod-disc spring system limits the maximum stretching and compression deformation of the inner metal rod relative to the outer metal pipe and reduces the impact effect of the inner metal rod on the outer metal pipe. When the structure bears the designed expected internal earthquake effect, the plastic deformation of the external metal energy dissipater can be utilized to dissipate earthquake energy, when the structure bears the large earthquake effect and the deformation of the structure is large, the angle brace can be degraded into stress support in the large deformation stage, the maximum deformation of the structure is limited, the lateral stiffness of the structure can be improved, and the structure can be protected. And the anti-collapse performance is improved.
本发明公开了一种碟簧并联金属消能器的变形受控隅撑，包括内金属杆、外金属管、备用拉杆‑碟簧系统、外置金属消能器。内金属杆插入外金属管内部，并在其内部用备用拉杆‑碟簧系统进行连接，在外表利用外置金属消能器进行连接。备用拉杆‑碟簧系统与外金属管固定连接，与内金属杆可滑移连接。备用拉杆‑碟簧系统限制了内金属杆相对于外金属管的最大拉伸与压缩变形，并且减少内金属杆对外金属管的冲击作用。当结构承受设计预期内地震作用时，本发明可利用外置金属消能器的塑性变形耗散地震能量，当结构承受大震作用且结构变形较大时，本发明隅撑可在大变形阶段退化成受力支撑，限制结构的最大变形，有利于提高结构的抗侧刚度，提升抗倒塌性能。
