Buckling restrained brace with single cable-stayed expansion property
The invention discloses a buckling restrained brace with a single cable-stayed expansion property, and particularly relates to the field of auxetic materials and the field of shock absorption and isolation of buildings, and the buckling restrained brace is composed of a core unit, a restraining unit and a sliding mechanism unit. The shape of the core unit is optimally designed, the idea that a traditional buckling restrained brace uses a solid long and thin strip plate as the core unit is abandoned, the steel plate with the auxetic effect and in a four-chiral hole structure arrangement mode is adopted, and the monoclinic property can be reflected when deformation is large. Compared with the prior art, the buckling restrained brace has the advantages that the buckling restrained brace solves the problem that a traditional common brace is often fractured in advance due to buckling deformation when an earthquake occurs; and tension-compression balance under circulating and reciprocating loads is achieved, the hysteresis performance is more stable, the energy dissipation capacity is more excellent, and in other words, the anti-seismic performance is higher.
本发明公开一种具有单斜拉胀性质的屈曲约束支撑，具体涉及拉胀材料领域及建筑减震隔震领域，所述屈曲约束支撑由核心单元、约束单元和滑动机制单元组成。本发明对核心单元的形状进行了优化设计，放弃了传统屈曲约束支撑使用实心细长条板作为核心单元的思想，而是采用具有拉胀效应的四手性孔洞结构排布方式的钢板，在变形较大的时候能体现出单斜的性质。与现有技术相比，本发明的优点为：所述屈曲约束支撑不仅解决了传统的普通支撑在地震发生时常因屈曲变形而提早断裂的问题，而且通过四手性孔洞结构排布的方式，实现了在循环往复荷载下的拉压平衡、拥有更加稳定的滞回性能以及更加优越的能量耗散能力，即具有更强的抗震性能。
