Deformation-controlled knee brace with external metal energy dissipater
The invention discloses a deformation controlled knee brace with an external metal energy dissipater. The deformation controlled knee brace comprises an inner metal rod, an outer metal pipe, a standby pull rod system, a connecting plate, a pressed elastic cushion block and the external metal energy dissipater. The inner metal rod is inserted into the outer metal pipe and connected through the standby pull rod system inside the outer metal pipe, and the outer surface of the inner metal rod is connected through the external metal energy dissipater. A pressed elastic cushion block is arranged at the bottom end in the outer metal pipe. The standby pull rod system limits the maximum tensile deformation of the inner metal rod relative to the outer metal pipe, and the pressed elastic cushion block reduces the impact effect of the inner metal rod on the outer metal pipe. The angle brace has the beneficial effects that when the structure bears the designed expected internal earthquake effect, the earthquake energy can be dissipated through plastic deformation of the external metal energy dissipater, and 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, the maximum deformation of the structure is limited, and the earthquake energy can be dissipated. The lateral stiffness of the structure is improved, and the anti-collapse performance is improved.
本发明公开了一种带有外置金属消能器的变形受控隅撑，包括内金属杆、外金属管、备用拉杆系统、连接板、受压弹性垫块、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系统进行连接，在外表利用外置金属消能器进行连接。外金属管内部底端有受压弹性垫块。备用拉杆系统限制了内金属杆相对于外金属管的最大拉伸变形，受压弹性垫块减少内金属杆对外金属管的冲击作用。本发明实现的有益效果是：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。
