Recoverable bistable impact-resistant additional structure
A recoverable bistable impact-resistant additional structure comprises a high-damping support and an impact panel which are arranged on the outer side of a building wall, and a plurality of bistable impact-resistant units are arranged between the high-damping support and the impact panel in multiple rows, multiple columns and multiple layers. According to the bistable anti-impact unit, structure and material elastic energy absorption is mainly adopted in the pre-impact stage, more energy is absorbed in the later elastic stage, meanwhile, the energy absorption efficiency is larger than the energy release efficiency, and the bistable anti-impact unit has the advantages that the energy absorbed by the structure in the elastic stage is larger than that of a traditional solid structure, lossless energy consumption can be achieved under rated energy, and the energy absorption efficiency is higher than that of the traditional solid structure. The original shape can be recovered after the impact energy is absorbed; and the anti-impact efficiency is excellent.
一种可恢复双稳态抗冲击附加结构，包括建筑墙体外侧设置的高阻尼支座及冲击面板，所述高阻尼支座与冲击面板之间成多排多列且多层布置有若干双稳态抗冲击单元；本发明的双稳态抗冲击单元实现了在冲击前阶段主要以结构及材料弹性吸能为主，后面的弹性阶段吸能更多，同时吸能效率大于放能效率，其优势在于，结构在弹性阶段吸收的能量大于传统实体结构，在额定能量下，能够实现无损耗能，并在吸收冲击能量后可以恢复原状；具有优异的抗冲击效率。
