The concept of a novel origami energy dissipation brace (OEDB) was proposed in this paper based on the folding pattern of Miura and Tachi unit cell. Creases introduced can induce OEDBs to deform in a predetermined manner Then, three low-carbon steel specimens were designed to examine how folding angle influences the brace hysteretic behavior. Experimental results showed that the failure of three specimens was caused all by the fracture of the central weld. The results also presented the variation tendency of the key mechanical characteristics of the specimens according to the changing origami folding angle, including hysteresis curves, skeleton curves, CPD, ductility, unbalance coefficient of tension and compression, equivalent viscous damping ratio, and strain distribution.

本文基于 Miura 和 Tachi 晶胞的折叠模式，提出了一种新型折纸能量耗散支架 (OEDB) 的概念。引入的折痕会导致 OEDB 以预定方式变形 然后，设计了三个低碳钢试样来检查折叠角度如何影响支撑的滞后行为。实验结果表明，三个试件的失效都是由中心焊缝断裂引起的。结果还给出了试样关键力学特性随折纸折叠角度变化的变化趋势，包括滞后曲线、骨架曲线、CPD、延性、拉压不平衡系数、等效粘滞阻尼比和应变分布。
